The 2. 5. 5 billion, 2. CH 5. 3K program will define the long term future of the US Marine Corps medium heavy lift capabilities and may be needed to save Marine aviation in the medium term. On average, existing CH 5. E aircraft are more than 1. Not to mention the resulting 2. According to Janes Defense Weekly, a 1. In Your Absence 2008 En Tu Ausencia. The USMC expected that the existing fleet would start to reach this point in 2. The funding profile below suggests a problem for the Corps The Marine Corps itself is the source of the disconnect. The HLR program initially called for 1. CH 5. 3E Super Stallion design, with initial flight tests in 2. IOC in 2. 01. 4 2. IOC was defined as a detachment of 4 aircraft, with combat ready crews, and prepared to deploy with all required equipment and spares. In 2. 01. 0, however, the Marines grew the program plan to 2. FY 2. 01. 3, and IOC back to FY 2. The program wasnt experiencing problems, and no reasons were given, beyond statements concerning the programs aggressive schedule. Further slippage has occurred since. Heres the full timeline Up, up, andclick to view fullThe current schedule creates a number of risks for the Marine Corps. Theres no question that pushing the CH 5. K program back will leave the Marines with a dwindling heavy lift helicopter fleet, whose size, capability, and safety are governed by mechanical realities rather than political diktat. In April 2. 01. 0, the US military ran out of stored CH 5. DE airframes to refurbish and return to the front lines. In February 2. 01. USMC retired its CH 5. D fleet altogether. The other risk is political. On the one hand, the CH 5. K is a large program, and the farther the Marines push it away, the easier it is to cut amidst budget crises. With its heavy lift fleet dwindling, that could be disastrous for the force. On the other hand, budgetary crises also look for programs that are late or experiencing problems, and the CH 5. K is big enough to earn a lot of attention if its seen as screwing up. That fact that the original schedule was overly aggressive wouldnt be remembered. Was the move to push the CH 5. K back an act of political negligence, to protect less critical programs like the V 2. Or was it an act of supreme prudence, which will lead to a strong program that survives precisely because it goes out and meets its targetsOpinions vary. Time will tell. Current Status.

As the development timeline stretched out, 6 System Development Test Aircraft were added to to that mix. To date, Sikorskys industrial partners include The CH 5.

Its being designed to carry a cargo load of 2. Fahrenheit. This is nearly double the capacity of the current CH 5. E Super Stallions, all in a helicopter thats roughly the same size. Those altitude and temperature qualifications matter, too, because hot and high conditions lower aircraft load carrying capabilities and combat radius especially for helicopters. This reduced performance has recently been a factor during operations in Afghanistan and relief efforts in Pakistan, for instance, and has been a factor with earlier models of the C 1. Hercules as well. Figures for the CH 5. K operating entirely around sea level and in cooler temperatures would be higher, but would not be double that of existing CH 5. Es. As an example of these variables at work, Sikorskys CH 5. K brochure states that the improved CH 5. K will have a maximum external load of 1.

MRAP RG 3. 1, IEDedclick to view storyEven at sea level, however, increased lift capacity will be important. As the Hummers fundamental lack of survivability began to marginalize it on the battlefield, the Marines led the charge to field MRAP blast resistant vehicle designs instead. While an up armored HMMWV weighs about 9,1. Category 1 MRAP patrol vehicles check in at weights ranging from 1. JLTVs that will replace a large segment of the HMMWV fleet are expected to weigh 1. Those weights mean that tactical operations to airlift mobile forces ashore beyond the beach, or within the zone of operations, will have only one helicopter available that can get the job done the CH 5.

No one technology constitutes a big stretch, which is good news for the program. Instead, a host of technologies that have been developed since the CH 5. E program will be refined, and used in inter related areas. For the basic outlines of many low risk CH 5. XCH 5. 3K improvements, read http www. An Affordable Solution To Heavy Lift PDF by Lt. Col. James C. Garman, an H 5. Senior Preliminary Design Engineer in Sikorskys New Product Definition Group. See also this interview with former HLR program manager Col. Paul Croisetiere. The most important new addition to the CH 5. K will be its 7,5. GE3. 8 T4. 08 engines, which have already hit 8,3. The military is hoping for 1. T6. 4 engine, even though the engine would produce 5. To improve maintenance and reliability, the GE3. Other technologies slated for the CH 5. K include a glass digital cockpit that has high commonality and interoperability with existing Army and Navy helicopters, high efficiency rotor blades with anhedral tips that have 1. Changes will be made as the program progresses, and engineers get a better sense of which technologies are ready, and which would create risks to the program. For example, the CH 5. K was going to use a viscoelastic lag damper for the rotors, in order to minimize vibration and stress. It was removed in order to speed up deployment, and a modified version of standard linear hydraulic dampers will be used instead. The Navy hopes to achieve 2x reliability compared to the existing CH 5. Es, but gave up the potential for 4x reliability, in exchange for less development risk. Sikorsky on CH 5.
