The US Marines’ helicopter force is aging on all levels, from CH-46 Sea Knights far older than their pilots to the 1980s era UH-1N Hueys and AH-1W Cobra attack helicopters that make up the Corps’ helicopter assault force. While the V-22 program has staggered along for almost 2 decades under accidents, technical delays, and cost issues, replacement of the USMC’s backbone helicopter assets has languished. Given the high-demand scenarios inherent in the current war, other efforts are clearly required.

Enter the H-1 program, the USMC’s plan to remanufacture 100 of the Marines’ old UH-1N Hueys and 180 of its AH-1W Super Cobra attack helicopters into advanced variants. The new versions would discard the signature 2-bladed rotors for modern 4-bladed improvements, redo the aircraft’s electronics, and add improved engines and weapons to offer a new level of performance. At least, that was the idea. It hasn’t quite worked out that way, and the H-1 program has encountered its own share of delays and issues. Nevertheless, the program survived a recent review, and continues on into the low-rate initial production stage and OpEval Phase II.

This is DID’s FOCUS Article regarding the H-1 program; it will be updated and backfilled as events and opportunity dictate. Recent developments include an IOC declaration for the UH-1Y, which paves the way for its upcoming deployment to the front lines. Unfortunately, other reports point to delivery delays in the program…

UH-60M: torch passed
(click to view full)

Back in April 2005, “UH-60M Black Hawk Replacements Get Fast Track” noted that “A full-rate production decision to authorize more than 1,200 UH-60M aircraft is scheduled for 2007.” They made it.

On Dec 12/07, Sikorsky Aircraft Corp. signed a 5-year, multi-service contract in Huntsville, AL for 537 helicopters to be delivered to the U.S. Army and Navy. The “Multi-Year VII” contract covers UH-60M Black Hawk troop transport and light cargo helicopters, and HH-60M SAR / MEDEVAC helicopters. These 2 platforms will replace the Army’s current UH-60 Black Hawk fleet, while the US Navy’s MH-60S and MH-60R Seahawk aircraft will replace the Navy’s existing SH-60B/F Seahawks, HH-60 CSAR, UH-3H Sea Kings, CH-46D Sea Knights, and HH-1N Huey SAR helicopters.

Now, substantial orders are being placed – and DID has the total order breakdown to date. The latest addition involves support for Bahrain’s new UH-60Ms…

TU-142: headed out?
(click to view full)

In November 2005 article, DID covered India’s $133 million deal for two P-3C Orion maritime-optimized patrol and surveillance planes. As it happens, that deal fell through on grounds of expense, support costs, and timing. Apparently, it would have taken 18-24 months for the US Navy to retrofit the two aircraft to the Indian Navy specifications once the lease had been finalized.

In December 2005, India’s navy floated an RFP for 8 new maritime aircraft. Subsequent statements by India’s Admiral Prakash indicate that they could be looking for as many as 30 aircraft by 2020. Lockheed was invited to bid again, and so were several other firms. The bids were submitted in April 2007. The plan was for price negotiations to be completed by 2007, with first deliveries to commence within 48 months.

India’s Ministry of Defence has extreme problems with announced schedules, but their existing fleet is wearing out, international requests for India’s maritime patrol help are rising, and some action is necessary. DID discusses the geopolitical drivers, the current fleet, and the known competitors.

Now that the bids have been submitted, technical evaluations have taken place, and price negotiations have reportedly wrapped up, we seem to be inching toward a winner…

Testing, testing…

Perhaps you’ve had this experience with your car. A warning light goes on intermittently, or another system doesn’t seem to operate reliably. The car goes in to the mechanic, where it may or may not display any symptoms. Repeat as required. Eventually, the dreaded diagnosis is given: electrical issues. The problem may or may not be consequential. The fix will be uncertain. The experience will be maddening.

For a military pilot and their maintenance crew, electrical issues are inherently more serious – but no less maddening. Few of us can afford to pay a mechanic for 24 hours of work in order to diagnose an electrical fault, but militaries often do so. Now consider the long-term effects on wiring from the constant airframe vibrations produced by high-energy turbines, and the buffeting produced by travel at several hundred miles per hour. Especially in a machine that may be 30 years old or more, while still possessing some of its original wiring.

As military aircraft fleets continue to age, wiring diagnosis and product improvements will be critical. The F-35 Joint Strike Fighter program is beginning to introduce production innovations involving self-diagnostic wiring, but what about existing aircraft without a full wiring refit? Enter a US NAVAIR project, and a product made by Eclypse International…

UH-60L: Leaving the LZ
(lick to view larger)

On July 20/06, the US DSCA announced [PDF format] Saudi Arabia’s official request to buy 24 UH-60L Utility/Assault Black Hawk helicopters, spare and repair parts, communications and support equipment, publications and technical data, personnel training and training equipment, contractor engineering and technical support services and other related elements of logistics support. The UH-60L Black Hawk is currently the USA’s mainstay utility helicopter, serving in various configurations in all operating theaters and theaters of war; the upgraded UH-60M is just entering low-rate production.

Now, that has turned into an actual contract…

The V-22 program has been beset by controversy throughout its 20-year development period, from crashes that have killed more than 20 Marines, to engine stalls, to issues with their AE1107C Liberty engines in Iraq that may lead to the end of Power By the Hour maintenance arrangements, or even replacement of the Liberty engines altogether. DID’s “V-22 Osprey: A Flying Shame?” offers a focused look at a number of specific allegations associated with the program, with material from Pentagon test reports, critical reviews, and the US military’s responses.

Despite these issues, the program continues to move forward. In March 2008, the Bell Boeing Joint Project Office in Amarillo, TX received a $10.4 billion modification that converted the previous advance acquisition contract (N00019-07-C-0001) to a fixed-price-incentive-fee, multi-year contract. The new contract will be used to buy 141 MV-22 (for USMC) and 26 CV-22 (Air Force Special Operations) Osprey aircraft, including associated manufacturing tooling in support of production rates.

This DID article will cover V-22 multi-year purchase contracts, developments that arise after this contract conversion, and associated contracts for key V-22 systems. The latest contract involves the next phase of the CV-22’s development, as testing and preparation for OpEval continues…

PAF F-16A drops Mk.82s
(click to view full)

On June 30/08, “US GAO Criticizes CSF Aid to Pakistan” discussed some of the tensions inherent in US aid to Pakistan, which has totaled several billion dollars since 2001. In addition to accounting and documentation issues, there have also been several instances in which the Pakistani military’s priorities and uses of its funds have diverged from the counter-terror focus intended by the US government.

Pakistan’s current status as a country with a larger and more active insurgency than Iraq’s has two seemingly paradoxical effects. On the one hand, it raises the stakes when “Coalition Support Funding” and other counter-terror aid is used for other military efforts or prestige projects instead. On the other hand, because the stakes are so high given Pakistan’s ownership of nuclear weapons, the USA’s leverage for dealing with questionable appropriations is reduced to some extent. Aid to Pakistan has always been as much about keeping its military and government on side as it has been about dealing with the Al-Qaeda/Taliban networks that currently control significant sections of the country along the Afghan border.

In late July 2008, all of these tensions exploded into view, as Pakistan proposed to redirect 2/3 of its 2008 aid into modernizing its older F-16 fighter fleet. The PAF wants to bring all of its F-16s to a standard that’s comparable to the new F-16 Block 50/52 aircraft it’s about to receive. The US State Department acquiesced; but Congress seems to be of a different mindset…

SOAR’s AH-6J
(click to view full)

July 30/08: The US Defense Security Cooperation Agency announces Iraq’s formal request to buy 24 helicopters. Based on the request, Iraq seems to be interested in Armed Reconnaissance Helicopters that act as scouts, perform light close air support, and escort other helicopters on dangerous missions.

The IqAF currently relies on a small force of Russia’s popular Mi-8/17 and refurbished Bell “Huey II” helicopters. While the Russian helicopters can be armed, their status as Iraq’s only medium utility helicopters makes them a poor fit for an ARH role. Instead, Iraq looks set to choose between 2 competitors. One is the Bell 407, whose derivative ARH-70A won the competition in America but has run into trouble. The other is Boeing’s AH-6 “Little Bird” light attack helicopters used by US Special Forces, which provided critical fire support during the 1991 “Backhawk Down” incident.

The complete request also includes mortars for land use, but also adds airborne weapons – something the nascent post-Saddam IqAf has not really had to this point. The entire request, which could be worth up to $2.4 billion, includes:

JHL: QTR Concept
(click to view full)

In 2005, the US military and NASA announced the kickoff of the Army-led Joint Heavy Lift program, with the award of 5 contracts for the Concept Design and Analysis (CDA) of a Vertical Takeoff and Landing (VTOL) Joint Heavy Lift (JHL) rotorcraft. This is a futuristic aircraft that’s imagined as having the C-130 Hercules aircraft’s 20 ton cargo capacity, but with the ability to take off and land like a helicopter. No current US military helicopter platform even comes close to that vision, and so the competitors are deploying some radical and different technologies in their attempts to meet these goals. DID covers each of them below.

CH-53E Super Stallion

At the same time, the US Marine Corps’ vital medium-heavy lift CH-53E Super Sea Stallion helicopters are beginning to to wear out their airframes. Hence the HLR Heavy Lift Replacement (HLR) program, aimed at fielding new-build CH-53K aircraft beginning in 2013-2015. The US Air Force, meanwhile, has its AJACS program, which aims to produce a C-130 replacement beginning around 2020.

All 3 programs may face a rough ride ahead. Runaway cost growth on numerous US defense programs, operational demands, and a looming demographic crisis in social programs all work to create budget squeezes, and hence pressures for program consolidation. The USMC’s affordable CH-53X track upgrade was very nearly sidetracked via a merger with he R&D heavy, schedule-uncertain, JHL, and may not be in the clear yet. The USAF’s AJACS program to replace the C-130 Hercules with a modern 20+ ton transport is also facing scrutiny of this sort, and those pressures, too may increase. Conversely, it is also possible that the JHL program could find itself edged out by a pair of more conventional helicopter and aircraft solutions from the USMC and USAF. DID notes the technologies, the politics, and progress to date.

Recent news includes a report that shows just how far away the US military is from a viable competition and winning design…

Replacement required
(click to view full)

War takes its toll on equipment, as well as men. In some cases, it wears out. In other cases, enemy fire or accidents destroy equipment. The USA has recognized this fact by funding wartime replacement expenditures as supplemental funding, which is outside the normal budgetary process. The intent is that this money will be spent on replacing equipment that has been worn out, damaged or destroyed, or will be used to provide specialized capabilities like MRAP mine-resistant vehicles that are directly related to the demands on the front lines. Admittedly, this hasn’t always been true. Politicians are what they are, and so are large organizations like the military. One area where this ethic has undoubtedly been honored, however, has been the AH-64 Apache attack helicopter fleet.

AH-64s are in very heavy demand as escorts for other helicopters in the war zones, to the point that the AH-64 fleet had logged more than 2 million flight hours by April 2006 – nearly 1/3 of which had been logged after Sept. 11/01. Apaches have also taken losses in combat. Even armor rated to stop 23mm cannon shells may not survive a missile hit, and helicopters are relatively fragile aircraft that can be seriously damaged if they take enough fire in smaller calibers, or endure an unlucky strike in the wrong place.

This article covers US Army Wartime Replacement Aircraft (WRA) AH-64D Longbow buys, which are the only truly new attack helicopters in the America’s inventory. Travis Williams, Boeing’s AH-64D WRA Program Manager helped to put these purchases in context within the overall Apache program, which is preparing for the new Block III model….
