CH-53K: The U.S. Marines’ HLR Helicopter program | P2170-016 exam Questions and Test Prep
Sep 02, 2021 04:fifty eight UTC via defense trade every day team of workerslatest update [?]
Takeoff?
September 2/21: Low cost initial construction Sikorsky gained a $48 million deal, which procures eight spare part and management and birth of constituents in guide of the CH-53K low expense preliminary creation configuration plane. The CH-53K will also be fielded from amphibious assault ships for the transportation of personnel and machine. Work will take region in Connecticut, Massachusetts, Washington, UK, Canada, California and North Carolina. Estimated completion may be in December, 2026.
CH-53K thought(click to view full)
The U.S. Marines have an issue. They rely on their CH-53E tremendous Stallion medium-heavy lift helicopters to movement troops, motors, and resources off of their ships. but the helicopters are wearing out. fast. The tempo demanded via the global struggle on Terror is relentless, and utilization quotes are three times usual. Attrition is taking its toll. during the last few years, CH-53s have been recalled from “boneyard” storage at Davis-Monthan AFB in Tucson, AZ, so as to maintain fleet numbers within the face of fresh losses and compelled retirements. Now, there are not any flyable spares left.
Enter the Heavy carry substitute (HLR) program, now regularly occurring as the CH-53K. It aims to present splendid performance advancements over the CH-53E, in the same airframe. The query is whether its provider entry lengthen to 2018-2019 will come too late to offset a significant decline in Marine aviation.
The HLR program Lifts Off
Sikorksy on HLR, 2011
The $25.5 billion, 200-helicopter CH-53K software will outline the long-time period way forward for the united states Marine Corps’ medium-heavy carry capabilities – and can be mandatory to store Marine aviation within the medium time period.
On ordinary, current CH-53E plane are more than 15 years historical, have over three,000 flight hours under hard circumstances, and are becoming further and further of a maintenance problem with a forty four:1 protection man-hours:flight hours ratio. no longer to mention the ensuing $20,000 per flight-hour can charge ratio. in keeping with Jane’s protection Weekly, a 1999 analysis confirmed that the existing fleet has a carrier life of 6,120 flight hours, in line with fatigue on the weakest aspect the place the tail folds. The USMC anticipated that the current fleet would beginning to reach this point in 2011, at a rate of 15 aircraft per year. The funding profile below suggests a problem for the Corps:
The Marine Corps itself is the source of the disconnect. The HLR program at the start known as for 156 new-construct helicopters derived from the CH-53E super Stallion design, with preliminary flight assessments in 2010-2011, and preliminary operating capability (IOC) in 2014-2015. IOC became defined as a detachment of four plane, with fight equipped crews, and prepared to install with all required equipment and spares.
In 2010, despite the fact, the Marines grew the program plan to 200 helicopters, whilst they pushed its preliminary flight lower back to FY 2013, and IOC returned to FY 2018. The application wasn’t experiencing issues, and no reasons were given, past statements concerning the software’s aggressive agenda. additional slippage has took place due to the fact. here’s the complete timeline:
Up, up, and…(click on to view full)
The existing time table creates a couple of dangers for the Marine Corps. There’s no doubt that pushing the CH-53K application returned will depart the Marines with a dwindling heavy-carry helicopter fleet, whose dimension, potential, and security are governed by using mechanical realities in preference to political diktat. In April 2010, the united states military ran out of saved CH-53D/E airframes to refurbish and return to the entrance traces. In February 2011, the USMC retired its CH-53D fleet altogether.
The other risk is political. On the one hand, the CH-53K is a large software, and the farther the Marines push it away, the easier it's to cut amidst funds crises. With its heavy-raise fleet dwindling, that can be disastrous for the drive. having said that, budgetary crises additionally look for programs that are late or experiencing issues, and the CH-53K is massive satisfactory to earn loads of attention if it’s considered as screwing up. That fact that the usual time table was overly aggressive wouldn’t be remembered.
become the flow to push the CH-53K back an act of political negligence, to protect less essential classes like the V-22? Or became it an act of supreme prudence, for you to cause a robust program that survives exactly since it goes out and meets its targets? Opinions range. Time will inform.
existing reputation
Some assembly required(click on to view full)
US Navy PMA-261 is responsible for the CH-53K program. Sikorsky is at the moment working below a $three.5 – four billion gadget construction and Demonstration (SDD) contract, to include 4 SDD flight check helicopters, 1 floor examine airframe, and linked software management and check aid. because the development timeline stretched out, 6 gadget construction verify aircraft had been delivered to to that combine. up to now, Sikorsky’s industrial partners consist of:
Mission example(click on to view full)
The CH-53K’s maximum gross weight (MGW) will increase to 88,000 pounds with external loads, versus seventy three,500 kilos for the CH-53E. MGW with inside hundreds can be 74,000 pounds, in comparison to 69,750 kilos for the CH-53E. It’s being designed to raise a cargo load of 27,000 pounds (13.5 tons) one hundred ten nautical miles, working at an altitude of 3,000 toes and an ambient temperature of 91.5 levels Fahrenheit. here is essentially double the capability of the latest CH-53E tremendous Stallions, all in a helicopter that’s roughly the equal dimension.
those altitude and temperature skills remember, too, as a result of “sizzling and excessive” situations decrease aircraft load carrying capabilities and fight radius – especially for helicopters. This decreased efficiency has these days been an element during operations in Afghanistan and relief efforts in Pakistan, for instance, and has been an element with earlier models of the C-a hundred thirty Hercules as well. Figures for the CH-53K operating wholly around sea stage and in cooler temperatures could be greater, however would now not be double that of existing CH-53Es.
as an example of these variables at work, Sikorsky’s CH-53K brochure states that the more advantageous CH-53K may have a maximum exterior load of sixteen.3t/ 36,000 lbs. in spite of this, an operation that incorporates an externally-slung load from sea degree to a point three,000 toes above sea level, with a total latitude there and again of 220 nautical miles/ 407 km, and 30 minute loiter at the landing zone, would have a maximum mission load of only 12.25t/ 27,000 lbs.
MRAP: RG-31, IEDed(click to view story)
Even at sea stage, however, elevated raise capacity could be crucial. as the Hummer’s fundamental lack of survivability begun to marginalize it on the battlefield, the Marines led the charge to field “MRAP” blast-resistant automobile designs in its place. while an up-armored HMMWV weighs about 9,a hundred kilos empty, the lightest class 1 MRAP patrol vehicles check in at weights ranging from sixteen,000 – 31,000 kilos, and even the “gentle” JLTVs with the intention to change a big phase of the HMMWV fleet are expected to weigh 14,000 – 20,000 pounds.
those weights mean that tactical operations to airlift cellular forces ashore beyond the seashore, or inside the zone of operations, will have only 1 helicopter available that can get the job done: the CH-fifty three.
If the Marines consider their CH-fifty three fleet is seeing heavy use now, simply wait.
New technologies
CH-53K conception(click to view full)
in order to meet those requirements, the CH-53K can be depending on a number of new technologies. no person know-how constitutes a big stretch, which is respectable news for the application. in its place, a host of applied sciences which have been developed given that the CH-53E software will be sophisticated, and utilized in inter-linked areas. For the simple outlines of many low-possibility CH-53X/CH-53K advancements, study “an inexpensive solution To Heavy elevate” [PDF] via Lt. Col. James C. Garman, an H-fifty three household pilot and Senior Preliminary Design Engineer in Sikorsky’s New Product Definition community. See additionally this interview with former HLR application manager Col. Paul Croisetiere.
probably the most essential new addition to the CH-53K should be its 7,500shp classification GE38 / T408 engines, which have already hit 8,300 shp in floor exams. The military is hoping for 18% more suitable certain gasoline consumption than the similarly sized T64 engine, however the engine would produce 57% extra power. To enrich preservation and reliability, the GE38 is additionally anticipated to have sixty three% fewer ingredients.
different technologies slated for the CH-53K include a “glass” [digital] cockpit that has excessive commonality and interoperability with present military and Navy helicopters, high-efficiency rotor blades with anhedral guidance which have 12% (leading) and 15% (tail) extra floor enviornment, plus diverse development to deal with higher masses; a composite cuff attachment that attaches the leading blades directly to an elastomerically-articulated titanium rotor head, devoid of the want for specialized tools or diverse redundant fasteners; a cargo rail locking gadget; external cargo improvements, survivability enhancements, and enhancements designed to lengthen service lifestyles.
adjustments will be made as the software progresses, and engineers get a stronger feel of which technologies are ready, and which would create hazards to the application. as an example, the CH-53K was going to make use of a “viscoelastic lag damper” for the rotors, with the intention to cut vibration and stress. It become removed to be able to speed up deployment, and a modified version of common linear hydraulic dampers will be used as an alternative. The Navy hopes to achieve 2x reliability in comparison to the latest CH-53Es, but gave up the knowledge for 4x reliability, in exchange for much less building risk.
Sikorsky on CH-53K
Given the CH-53E’s tremendous upkeep ratio, reliability will rely. As former HLR program manager Col. Paul Croisetiere put it in a NAVAIR release:
“Given the CH-53E’s operational charges and preservation calls for, heavy elevate has built its acceptance for excellence on the backs of our maintainers… we're going to take our maintainers somewhere they’ve hardly been earlier than. domestic for dinner.”
a few a long time of weapon software heritage indicate that the percentages of meeting this intention are low. as an alternative, the trend is that these promises are made, but more advanced and sophisticated weapons wind up having more features of failure, and require even more upkeep. If the CH-53K program can spoil that cycle, it could signify a landmark success in Pentagon weapons acquisition.

may 31/13: antagonistic IG report. The Pentagon’s Inspector commonplace issues a document beneath Audit challenge No. D2012-D000CD-0037.000, telling the USMC that the CH-53K’s software increase to 200 helicopters isn’t justified. The Marines courteously inform the IG to stay it the place Chesty can’t discover it.
The Inspector commonplace’s statement that “the Marine Corps risks spending $22.2 billion in procurement and working and assist funding for forty four additional plane” is a blatant error – that’s the complete 2011 software charge for 200, plus R&D. past that, they bitch that the USMC:
In response, the USMC Deputy Commandant says the present analyses do justify it, and JROC authorized the 200. Then the Milestone choice Authority approves the Marine Corps’ request to rebaseline the program with a fifty four% procurement charge increase over the 2005 baseline (a jump from Dec 2011 figures, if genuine) and formally push the Milestone C choice from December 2012 to February 2016 (later than the present August 2015). The IG wants extra comments re: the re-baselining. Which is great, so far as it goes, however the complete process seems like an ad for the Lexington Institute’s Daniel Goure, who argues that the Pentagon’s procurement procedures are an out of handle overhead burden. It’s all about paper, rather than the soundness of the conclusion. and you may’t use what you gain knowledge of in war video games to alternate procurement choices? What fool thinks that’s a good suggestion? Pentagon IG file.

“CH-53K Heavy raise alternative Helicopter – application prices multiplied $1,897.6 million (+7.1%) from $26,626.8 million to $28,524.four million, due basically to changing the charge estimating methodology from analogy-based to business enterprise backside-up (+$1,796.6 million), use of commercial indices for materiel escalation costs (+$948.9 million), revised escalation indices (+$539.four million), a rise within the construction line shutdown estimate (+$one hundred twenty.7 million), and a rise in assist device, restoration of repairables, and spares charges (+$64.9 million). These increases have been partially offset via decreases in different support expenses (-$664.0 million), preliminary spares necessities (-$589.0 million), and the software of new inflation indices (-$385.3 million).”
to place the estimating into English, the program had estimated charges in response to an identical programs, however now they’ve long gone in the course of the chosen suppliers and developed an estimate the use of precise expenses for components and materials, plus industrial figures for raw substances and so forth. The influence provides essentially $2.85 billion to the software, and other can charge jumps carry the full raise to $3.forty seven billion. The downward revisions to spares and help, and to inflation, keep away from fees from rising over 13%.
Are the alterations low-budget? We won’t comprehend except flight trying out is well underway and time has published precise inflation fees, however there’s reason to be skeptical. It could be a case of “paper cuts now, then charge raises once construction is underway and jobs in Congressional districts are committed.” We’ll need to confer with the program to even begin to choose.

Aug sixteen/10: CH-35D plans. DoD Buzz appears on the shifting plans to change the USMC’s 30 CH-53D Sea Stallions. The usual plan was to replace them with MV-22s. At some aspect in 2007/08, the Marine Corps formally determined change their ageing CH-53Ds with CH-53Ks. however now USMC Lt. familiar Trautman is announcing that he wants an east coast and a west coast MV-22 squadron to replace the CH-53Ds in Afghanistan, and “When i will be able to try this, that’ll be the birth of getting CH-53 Delta out of ways.”
exactly what “out of ways” skill is ambiguous. If it skill out of provider, DoD Buzz appropriately notes that this raises questions in regards to the USMC’s guide for the CH-53K, and would appear to be more desirable news for the MV-22. If it means “shifted again to Hawaii whereas MV-22s serve in Afghanistan,” that might be some thing else. The accurate meaning isn’t one hundred% clear within the article.
Aug three/10: CDR. Sikorsky publicizes a successful essential Design assessment for its CH-53K, following every week-lengthy meeting in late July that included representatives from the militia, Sikorsky, and 21 industrial companions. on the assessment, the CH-53K team had to demonstrate that their design meets NAVAIR’s device necessities. gadget-stage performance projections indicate that each one 7 Key performance Parameters (KPPs) can be carried out with satisfactory risk mitigation margin constructed-in.

June 28/10: Sub-contractors. Raytheon Co. in El Segundo, CA received a $26.5 million enterprise-fixed-rate start order for 50 ahead looking infrared devices that can be geared up to CH-53E (42) and CH-53K (8) helicopters. Discussions with corporate representatives ascertain that these may be AN/AAQ-29 turrets, the use of a 480 x 640 element, 3-5 micron wavelength indium antimonite infrared detector, and a 2 container of view telescope on a 12-inch diameter turret.
here is a observe-on to a previous order. Work beneath this primary ordering contract should be performed in El Segundo, CA, and is anticipated to be complete in June 2012. $530,000 will expire at the end of the current fiscal yr, on Sept 30/10 (N00019-10-G-0018).
June four/10: No greater CH-53D/Es. US NAVAIR proclaims that it has delivered the last obtainable CH-53s from storage at AMARG in Tucson, AZ. The remaining H-53E to come out of wasteland retirement became dropped at Marine Helicopter practicing Squadron 302 on might also 7/10, whereas the final CH-53D became delivered April 16/10.
considering the fact that the beginning of the application in August 2005, FRC East H-fifty three artisans have inducted and accomplished 10 of the heavy-raise helicopters. The crew delivered eight CH-53Es and 2 CH-53Ds, a few of which had been idle for as many as 11 years, ahead of schedule and below funds. each and every helicopter nonetheless took about 25,000 complete work hours for all trying out, adjustments, and renovation. Sikorsky ended CH-fifty three construction in 1999, so AMARG was the remaining ultimate source of airframes.
Boneyard out of CH-53s
can also 10/10: Engine. Flight foreign reviews that even if the CH-53E is delayed, GE remains dedicated to delivering the 7,500 shp type GE38-1 engine on schedule. The firm sees re-engining opportunities and linked income past the CH-53K, so that they’ve begun supplying GE38s for ground exams years before airframes turn into attainable for flight check.
As of Feb 15/10, GE had recorded 176 engine begins and 177 working hours, with sustained energy of seven,760 shp and top energy of eight,300 shp. April 2010 noticed start of a 2nd engine for ground assessments.
The article is less fine about the CH-53K’s odds of successful the German/French heavy-raise helicopter software. apparently, Germany needs a helicopter so as to fit key automobiles internally, no longer underslung. in the end, the query should be no matter if Germany can manage to pay for to develop what it desires, can discover it elsewhere, or is forced to get rid of some necessities.
April 29/10: Why the delay? DefenseTech reviews that the USMC has pushed again the preliminary flight date of the CH-53K through 2 years to FY 2013, and preliminary Operational ability with the aid of 3 years to FY 2018, “with little concrete justification past an ‘overly aggressive preliminary program time table’ “, and while stressing that the program has not run into technical problems. Craig Hooper writes:
“The CH-53K turned into an unsung showpiece for these preaching the virtues of incremental construction, and, in consequence, appetite for the platform has grown through about 30 percent, with the program of listing anticipated to increase from 156 aircraft to 200. but, within the method, the CH-53K has become some thing of a MV-22-killer. is this the difficulty?… In late 2009, the Marine Corps decided to go with the CH-53Ks to replace their forty-yr ancient CH-53D fleet (MV-22 Ospreys have been initially slated to substitute the CH-53D). At about the identical time, Israel decided to forego the Osprey for the CH-53K, killing the Osprey’s top of the line hope of snaring a global purchaser. And with the Osprey 65% availability and the MV-22s excessive working prices of about $11,000 bucks an hour… worse, reports from the Pentagon validated that a CH-53K-outfitted big-deck amphib supplied a lot more logistical assist for embarked Marines than the MV-22… Slowing CH-53K development will… steer clear of precise-records comparisons between systems… [until] a 2d multi-yr MV-22 contract gets signed in FY 2013. Even worse, slowing the CH-53K agenda raised the software price with the aid of at the least $1.1 billion greenbacks, elevating the per-unit expense… Why sluggish a application that stands to be a excessive-demand showpiece with expertise markets in Israel, Germany, France, Turkey, Singapore and Taiwan?”
requested for a response, US MARCORSYSCOM spoke of that US NAVAIR become the simplest company that could respond; NAVAIR did not respond to DID’s simultaneous inquiry.
April 1/10: SAR – program grows. The Pentagon releases its April 2010 chosen Acquisitions document, protecting fundamental application changes as much as December 2009. The CH-53K is blanketed, since the Marines desire extra of them – but there’s a self-imposed capture:
“CH-53K – software charges elevated $6,817.8 million (+36.four%) from $18,708.3 million to $25,526.1 million, due primarily to a quantity boost of 44 plane from 156 to 200 aircraft (+$3,108.9 million), and raises in different aid prices (+$749.7 million) and preliminary spares (+$456.2 million) associated with the quantity boost. expenses also extended as a result of a three-yr delay in the procurement profile transferring preliminary purchases from fiscal 2013 to fiscal 2016 (+$1,148.four million), time table increase because of funding constraints (+$669.6 million), and an increase in the charge estimate for the construction contract (+$611.2 million).”

March 30/09: GAO. the USA GAO audit office offers its 7th annual “protection Acquisitions: Assessments of chosen Weapon classes file, which appears at forty seven programs including the CH-53K HLR. The CH-53K stands out, as some of the few courses to reveal reduce R&D projections (from $4.23 billion to $4.17 billion) and estimated start time (2 months early) seeing that its 2005 baseline. The certainty is, the Marines have little choice. The time crunch has already begun:
“in response to program officials, all attainable decommissioned CH-53E helicopters had been reclaimed… at present deployed CH-53E plane are flying at thrice the planned utilization expense… The application intends to fabricate up to 29 of the 156 total [CH-53K] helicopters (19 p.c) all the way through low-rate preliminary construction on the equal time that it is conducting initial operational testing. whereas concurrent checking out and construction may additionally support to box the programs sooner, it may also outcomes in stronger retrofit charge…”
That’s likely, since a number of necessities and systems were shelved, with the intention to carry the helicopter on time:
“both of the CH-53K’s present essential applied sciences, the main rotor blade and the leading gearbox, are immature and are anticipated to be totally mature following the low-expense preliminary production decision in 2013. The program changed a 3rd know-how, the viscoelastic lag damper, with a modified version of an existing [linear hydraulic damper] expertise. all through preparations for the preliminary design evaluate, it turned into found that maturing equipment engineering projects would probably require further charge and time. as a result, the application eliminated noncritical requirements to include costs and delayed the preliminary and critical design experiences and low-rate initial production decision.”

Appendix A: Flying Between Scylla and Charbydis: Navigating the Political Shoals
JHL: QTR thought(click to view full)
DID’s coverage of the HLR program has additionally protected a record about HLR’s capabilities merger with the us army’s futuristic JHL software. The Joint Heavy Lifter (JHL) is imagined as an plane with cargo means that processes a C-130 Hercules transport (about 20 lots), but with the skill to take off and land like a helicopter. No existing US armed forces helicopter platform even comes close. JHL’s rivals are deploying some radical and diverse technologies in their try and obtain these desires – from quad tilt-rotors to coaxial skycranes and even compound helicopters.
Marine Corps acquisition officers additionally weighed the option of participating in JHL. while Congress might always step in to force the subject – and can nonetheless do so – the Marine Corps notice that this may be deeply unwise for a couple of explanations:
“The military’s proposed heavy lift requirement to move the future combat device significantly exceeds our requirement,” said program supervisor, Col. Paul Croisetiere. “The genuine plane hasn’t been designed yet, however initial evaluation suggests the joint heavy lifter can be too big to function from current and programmed amphibious delivery. We may additionally have a use for it, however in more of a logistical position as a likely KC-130J [air tanker] alternative – we nevertheless want the CH-53K for tactical heavy carry.”
Joint Heavy Lifters might also not be purchasable any prior to 2025, in line with Croisetiere, which is more than 10 years after the Marine Corps will be compelled to beginning retiring its latest CH-53E fleet. notwithstanding the Marines might use it, Croisetiere stated that as currently estimated, JHL can be too massive to function from the Marines’ amphibious ships.
V-22 Osprey
here's a logical argument. although this motive could promote greater if the USMC hadn’t spent the last decade describing tilt-rotor expertise as the imperative wave of the long run that could make helicopters obsolete, in its quest to promote the $a hundred million per plane V-22 Osprey.
When budgets are also being squeezed tough through distinct can charge overruns on a wide swath of classes, classes that appear to be akin to each and every other will become large targets for Congressional cuts and force to merge. the united states Marines were the main provider advocates of tilt-rotor technology as a transformational necessity. Having invested so tons of their prestige and credibility within the V-22, some individuals on Capitol Hill seem to be inclined to view the Marines’ rejection of a program that contains equivalent Quad Tilt Rotor and OSTR (most advantageous speed Tilt-Rotor) alternatives as inconsistent, and therefore mere territoriality. If this view spreads, it'll not bode smartly for the HLR software’s political survival.
It certainly wouldn’t be the primary time in US defense force procurement historical past that the promise of the shiny new element has discovered itself within the approach of fulfilling military necessities with cheaper, proven alternatives.
MH-53J Pave Low IV(click to view alt.)
The natural response to such pressures would be twofold. One music would emphasize the comparatively speculative nature of the JHL software’s technologies and their uncertain construction timelines. The other music would tout the price of more cost-effective builds of proven helicopters, in order to meet instant wants and an uncompromising timeline for fleet airframe lifestyles. this is precisely what Col. Paul Croisetiere has done.
Making that argument, despite the fact, flies in the face of almost every little thing the USMC mentioned when some in Congress pushed for instantly obtainable widely wide-spread helicopter options to exchange the Marines’ extraordinarily aged Vietnam-period CH-46 Sea Knights. alternate options that might also have charge about half the cost per plane. If the CH-46s could be patched together by way of life extension courses and extensive upkeep while the V-22s sorted out their difficulties and finally reached creation decades late, why no longer the CH-53Es? above all if pursuing the same tilt-rotor know-how just like the JHL’s QTR would cut back the V-22’s per-aircraft fees while increasing universal interoperability, and for this reason easing lengthy-time period preservation and logistics prices as well?
These arguments can also or may also now not be regarded legitimate. nonetheless, they should completely be anticipated as the world war on Terror, unexpected future contingencies, and a looming demographic shift put expanding drive on US defense budgets. the us Marine Corps has certainly prepared the ground neatly.
The HLR software may have an eventful political event ahead of it.

As some extent of hobby, this is one of the most greater innovative advice we’ve seen re: the next-technology CH-53X. It proposes turning the CH-53 right into a “Skycrane” variant, and the use of it together with the vogue towards “combat field” containerized forces, plus underslung mild armor & vehicles.
The thought is that this may enrich both the CH-53E’s capabilities (by way of decreasing aircraft weight but no longer vigor) and the United States’s transformational deployability (by way of faster and greater versatile load and ship that would additionally enrich tactical surprise).
