JSF’s F135 Engine Meeting Milestones

Lockheed Martin and Pratt & Whitney have successfully performed the first start of an F-35 Joint Strike Fighter aircraft test engine, using an integrated power package (IPP) that the functions traditionally performed by the auxiliary power system, emergency power system, and environmental control into a single system. The system was used to start a Pratt & Whitney F135 short-takeoff/vertical-landing (STOVL) engine at the company’s advanced test facility in West Palm Beach, FL. The IPP is a subsystem of the F-35 Power and Thermal Management System (PTMS).

The JSF program has targeted the successful IPP engine start as a major milestone since the beginning of the System Development and Demonstration phase of the program in 2001. The achievement paves the way for additional development testing in preparation for the F-35’s first flight in 2006, and comes about a month after the Pratt & Whitney F135 System Development and Demonstration (SDD) program successfully completed the post test Critical Design Review (CDR) by the Joint Strike Fighter (JSF) Joint Program Office (JPO). The JPO review found that the F135 propulsion system has met all review objectives and is on track to deliver the first flight test engine later this year.

MH-60R/S: The USA’s New Naval Workhorse Helicopters

The US Army’s UH-60 Black Hawks have always had a naval counterpart. SH-60B/F Seahawk/ LAMPS helicopters were outfitted with maritime radar, sonobuoys, and other specialized equipment that let them perform a wide variety of roles, from supply and transport, to anti-submarine warfare, search and rescue, medical evacuation, and even surface attack with torpedoes or Kongsberg’s AGM-119 Penguin missiles. Like their land-based counterparts, however, the Seahawks are getting older. The Reagan defense build-up is receding into history, and its products are wearing out.

European countries chose to build new designs like the medium-heavy EH101 and the NH90 medium helicopter. They’re larger than the H-60s, make heavy use of corrosion-proof composites, and add new features like rear ramps. The USA, in contrast, decided to upgrade existing H-60 designs for the Army and Navy. Hence the MH-60R Multi-Mission Helicopter (aka. “Romeo”) and MH-60S (aka. “Sierra”) Seahawks. MH-60Rs and MH-60Ss will eventually replace all SH-60B/F & HH-60H Seahawks, HH-1N Hueys, UH-3H Sea Kings, and CH-46D Sea Knight helicopters currently in the US Navy’s inventory. Both programs are underway, and will be covered in this DID FOCUS Article.

Turkey Finally Lands Its Attack Helicopters

Turkey has been looking to modernize its attack helicopter fleet since the mid-1990s, but the process has mostly served as an object lesson in how not to buy defense equipment. This competition faced many difficulties; after numerous snafus, technology transfer and production issues, and canceled competitions, all 3 invited American manufacturers had abandoned the competition entirely.

Even the “final” round seemed imperiled, following reports of the Turkish military’s deep dissatisfaction with the choices. Nevertheless, the competition survived long enough to pick a winner, and signed contracts with AgustaWestland. But Turkey didn’t just buy helicopters. They bought the A129 model – lock, stock, and rotor.

LCA Tejas: An Indian Fighter – With Foreign Help

India’s Light Combat Aircraft program is meant to boost its aviation industry, but it must also solve a pressing military problem. The IAF’s fighter strength has been declining as the MiG-21s that form the bulk of its fleet are lost in crashes, or retired due to age and wear. Most of India’s other Cold War vintage aircraft face similar problems.

In response, some MiG-21s have been modernized to MiG-21 ‘Bison’ configuration, and other current fighter types are undergoing modernization programs of their own. The IAF’s hope is that they can maintain an adequate force until the multi-billion dollar 126+ plane MMRCA competition delivers replacements, and more SU-30MKIs arrive from HAL. Which still leaves India without an affordable fighter solution. MMRCA can replace some of India’s mid-range fighters, but what about the MiG-21s? The MiG-21 Bison program adds years of life to those airframes, but even so, they’re likely to be gone by 2020.

That’s why India’s own Tejas Light Combat Aircraft (LCA) project is so important to the IAF’s future prospects. It’s also why India’s rigid domestic-only policies are gradually being relaxed, in order to field an operational and competitive aircraft. Even with that help, the program’s delays are a growing problem for the IAF. Meanwhile, the west’s near-abandonment of the global lightweight fighter market opens a global opportunity, if India can seize it with a compelling and timely product.

Adir Who? Israel’s F-35i Stealth Fighters

In an exclusive June 2006 interview, Israeli Air Force (IAF) chief procurement officer Brigadier-General Ze’ev Snir told Israeli media that the F-35 Joint Strike Fighter was a key part of their IAF recapitalization plans, and that Israel intended to buy over 100 of the fighters to replace their fleet of over 300 F-16s.

Since then, however, the expected cost of that purchase has more than doubled. Israel’s F-35 contract had to deal with that sticker shock, with issues like the incorporation of Israeli technologies and industrial work, and with major schedule slips in the core F-35 program. Israel was even contemplating delaying its purchase, which would have removed an important early adopter for the Lightning II. In the end, however, Israel decided to forego other fighter options, and became the first foreign buyer of operational F-35s. So, how is the “F-35i Adir” shaping up?

Saudi Shopping Spree: 24 UH-60L Black Hawk Helicopters, and more

On July 20/06, the US DSCA announced Saudi Arabia’s official request to buy 24 UH-60L Black Hawk helicopters, plus spares and 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 ramping up production, and is the subject of a 2010 DSCA request to equip Saudi Arabia’s National Guard.

Saudi Arabia recently issued the final piece of that contract.

UCLASS to be Descoped for CBARS Conversion AKA MQ-25 Stingray

The idea of UAVs with full stealth and combat capabilities has come a long way, quickly. Air forces around the world are pursuing R&D programs, but in the USA, progress is being led by the US Navy.

Their interest is well-founded. A May 2007 non-partisan report discussed the lengthening reach of ship-killers. Meanwhile, the US Navy’s carrier fleet sees its strike range shrinking to 1950s distances, and prepares for a future with fewer carrier air wings than operational carriers. Could UCAV/UCAS vehicles with longer ranges, and indefinite flight time limits via aerial refueling, solve these problems? Some people in the Navy seem to think that they might. Hence UCAS-D/ N-UCAS, which received a major push in the FY 2010 defense review. Now, Northrop Grumman is improving its X-47 UCAS-D under contract, even as emerging privately-developed options expand the Navy’s future choices as it works on its new RFP.

JMR-FVL: Army Casts Dice for Future Helicopters

The JMR-TD program is the science and technology precursor to the Department of Defense’s estimated $100 billion Future Vertical Lift program, which is expected to replace between 2,000-4,000 medium class UH-60 utility and AH-64 attack helicopters after 2030.

In reality, FVL will fall far short of that number if it ever goes ahead, but those figures are the current official fantasy. While they’re at it, the Pentagon wants breakthrough performance that includes the same hovering capability as smaller armed scout helicopters, and a 100+ knot improvement in cruising speed to 230+ knots. That’s almost certainly achievable, thanks to new developments that involve very different helicopter designs.

E-2D Hawkeye: The Navy’s New AWACS

Northrop Grumman’s E-2C Hawkeye is a carrier-capable “mini-AWACS” aircraft, designed to give long-range warning of incoming aerial threats. Secondary roles include strike command and control, land and maritime surveillance, search and rescue, communications relay, and even civil air traffic control during emergencies. E-2C Hawkeyes began replacing previous Hawkeye versions in 1973. They fly from USN and French carriers, from land bases in the militaries of Egypt, Japan, Mexico, and Taiwan; and in a drug interdiction role for the US Naval Reserve. Over 200 Hawkeyes have been produced.

The $17.5 billion E-2D Advanced Hawkeye program aims to build 75 new aircraft with significant radar, engine, and electronics upgrades in order to deal with a world of stealthier cruise missiles, saturation attacks, and a growing need for ground surveillance as well as aerial scans. It looks a lot like the last generation E-2C Hawkeye 2000 upgrade on the outside – but inside, and even outside to some extent, it’s a whole new aircraft.

LCS & MH-60S Mine Counter-Measures Continue Development

The US Navy currently uses large CH-53/MH-53 helicopters and towed sleds to help with mine clearance work, but they hope to replace those old systems with something smaller and newer. The MH-60S helicopter’s Airborne Mine Counter-Measures (AMCM) system adds an operator’s station to the helicopter cabin, additional internal fuel stores, and towing capability, accompanied by a suite of carried systems that can be mixed and matched. AMCM is actually 5 different air, surface and sub-surface mine countermeasures systems, all deployed and integrated together in the helicopter.

While the US Navy develops AMCM, and complementary ship-launched systems for use on the new Littoral Combat Ships, new minehunter ship classes like the Ospreys are being retired by the US Navy and sold. All in an era where the threat of mines is arguably rising, along with tensions around key chokepoints like the Suez Canal and Strait of Hormuz.

This article explains the components involved (AQS-20, ALMDS, AMNS, OASIS, RAMICS; COBRA, RMS, SMCM), chronicles their progress through reports and contracts, and provides additional links for research.
