Britain’s AW101 Merlin Helicopters: Upgrading the Fleet

As part of Britain’s fiscal rebalancing, The Royal Navy is set to inherent the RAF’s Merlin HC3/3A medium-heavy battlefield helicopter fleet, while simultaneously upgrading its existing set of Merlin HM Mk1s. The entire effort approaches $3 billion for a final total of 55 refurbished helicopters, and these refurbishments will be carried out as part of the AW101 fleet’s long-term maintenance plan.

The navy’s existing fleet is being progressively upgraded and returned to service, adding a range of technological improvements to the helicopter’s avionics, control systems, sensors, and radar. The Royal Navy received 44 EH101 Merlin HM1s between 1998-2002 for training, surface attack and anti-submarine warfare duties, and has since lost 2 in accidents. The remaining 42 helicopters are now expected to remain in service until 2029, though only 30-38 will be upgraded. Another 28 EH101 Merlin HC3/ HC3A medium support helicopters currently serve with the UK Royal Air Force, and they will join the Navy to succeed the Sea King Mk.4 Commandos as the Royal Marines’ battlefield helicopters.

Israel Announces F-16 Variant Upgrades

F-15s and F-16s make up the backbone of Israel’s potent fighter force. The IDF’s main fighter is the F-16 Fighting Falcon, including aging F-16 A/B Netz (“Falcon”), plus F-16C Barak (“Lightning”) and 2-seat F-16D Brakeets (“Thunderbolt”), and now the heavily customized two-seat F-16I Block 52+ Soufa (“Storm”). The Israelis fly the largest contingent of F-16s outside the United States, alongside longer range, higher performance F-15s. F-15A-D Baz (“Eagle”) models have greatly distinguished themselves in IDF service, and the customized two-seat F-15I Ra’ahm (“Thunder”) Strike Eagle is optimized for advanced ground attack and long range interception. All of these aircraft are heavily modified from the US versions, with Israeli avionics, self-protection systems, weapons, and sometimes radars as well.

While Israel’s F-16A/B Netz inventory may well be sold on the international market, their F-16 C/D and F-15 A-D planes were expected to serve the Air Force Corps until at least 2020. Unfortunately, Israel’s new F-35As won’t even start arriving until 2016 or 2017. To keep their edge, Israel began spending money in 2006 to improve and upgrade its legacy fighter fleet…

Snakes and Rotors: The H-1 Helicopter Program

The US Marines’ helicopter force is aging at all levels, from banana-shaped CH-46 Sea Knight transports that are 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 tilt-rotor V-22 Osprey 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 older helicopters into new and improved UH-1Y utility and AH-1Z attack helicopters. 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. It seemed simple, but hasn’t quite worked out that way. The H-1 program has encountered its share of delays and issues, but the program survived its review, and continued on into production and deployment.

DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This article covers the H-1 helicopter programs’ rationales and changes, the upgrades involved in each model, program developments and annual budgets, the full timeline of contracts and key program developments, and related research sources.

CH-53K: The U.S. Marines’ HLR Helicopter Program

The U.S. Marines have a problem. They rely on their CH-53E Super Stallion medium-heavy lift helicopters to move troops, vehicles, and supplies off of their ships. But the helicopters are wearing out. Fast. The pace demanded by the Global War on Terror is relentless, and usage rates are 3 times normal. Attrition is taking its toll. Over the past few years, CH-53s have been recalled from “boneyard” storage at Davis-Monthan AFB in Tucson, AZ, in order to maintain fleet numbers in the face of recent losses and forced retirements. Now, there are no flyable spares left.

Enter the Heavy Lift Replacement (HLR) program, now known as the CH-53K. It aims to offer notable performance improvements over the CH-53E, in a similar airframe. The question is whether its service entry delay to 2018-2019 will come too late to offset a serious decline in Marine aviation.

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.

Pakistan & China’s JF-17 Fighter Program

The FC-1/ JF-17 Thunder is a joint Chinese-Pakistani project that aimed to reduce Pakistan’s dependence on western firms for advanced fighters, by fielding a low-cost multi-role lightweight fighter that can host modern electronics and precision-guided weapons. It isn’t a top-tier competitor, but it represents a clear step up from Pakistan’s Chinese MiG-19/21 derivatives and French Mirage III/V fighters. This positioning addresses a budget-conscious, “good enough” performance market segment that the West once dominated, but has nearly abandoned in recent decades.

Pakistan has fielded JF-17s in squadron strength, with more on order and a Block II R&D program nearing completion. India’s competing Tejas fighter is overcoming project delays by looking to foreign component sources, but Pakistan and China remain out front with their offering, even though they began their project much later than India did. Pakistan and China have even set up a joint JF-17 marketing agency to promote export sales, which hasn’t paid off as quickly as they had hoped, but it would be unwise to count them out just yet…

UK Tornados Biding Time

With the retirement of the RAF’s Jaguar fleet, the core of Britain’s land-based tactical air fleet rests in a pair of multinational European fighters. The new Eurofighter Typhoon is one of the top 3 air superiority fighters in the world, and enhancements are finally beginning to give it some precision strike capability. The mainstay of the existing fleet is made up of the British-Italian-German Panavia consortium’s Tornado aircraft, in both F3 air defense and GR4 low-level precision strike configurations.

The F3s are being pushed aside by the Eurofighters, but the GR4s were expected to remain in place until 2025. A 2007 effort added LITENING surveillance and targeting pods, to improve the aircraft’s close air support capabilities on the front lines of Iraq and Afghanistan. Now a GBP 253 million (about $496 million) “Capability Upgrade Strategy (Pilot)” program seeks to take the next steps, and is intermeshed with the Tornado fleet’s successful ATTAC fixed-price through-life maintenance program…

UH-72 Lakota Light Helicopter Lands Airbus in US Defense Market

DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This is DID’s FOCUS Article regarding the US Army’s Light Utility Helicopter program, covering the program and its objectives, the winning bid team and industrial arrangements, and contracts.

The US Army’s LUH program will finish as a 325 helicopter acquisition program that will be worth about $2.3 billion when all is said and done. It aimed to replace existing UH-1 Hueys and OH-58 Kiowa utility variants in non-combat roles, freeing up larger and more expensive UH-60 Black Hawk helicopters for front-line duty. In June 2006, a variant of Eurocopter’s EC145 beat AgustaWestland’s AB139, Bell-Textron’s 412EP Twin Huey, and MD Helicopters’ 902 Explorer NOTAR (No Tail Rotor) design. The win marked EADS’ 1st serious military win in the American market, and their “UH-145” became the “UH-72A Lakota” at an official December 2006 naming ceremony.

Eurocopter has continued to field new mission kits and deliver helicopters from its Mississippi production line, while trying to build on their LUH breakthrough. A training helicopter win will keep the line going for a couple more years…

South Korea Launches KF-16 Fighter Upgrades Upended

In July 2009, The Korea Times reported that ROKAF was looking to upgrade its F-16C/D fleet’s radar and armament, as part of the 2010-2014 arms acquisition and management package submitted to President Lee Myung-bak for approval.

Under the Peace Bridge II and II deals, The ROKAF bought 140 “KF-16” Block 52 fighters, which were assembled in Korea between 1994-2004 under a $5.5 billion licensing agreement. Key upgrades to this fleet will include new radars to replace the existing APG-68v5/v7 systems, modern avionics and computers, and upgrades of the planes’ cabling and databuses to MIL-STD-1760. The centerpiece AESA radar competition has a winner now, and South Korea has picked its contractor for the overall upgrade program. Now the effort is turning that into binding contracts, and beginning the upgrade process. Other countries within the region and beyond are interested in similar high-value F-16 upgrade programs, so the ROk’s experiences will be watched carefully.

Japan Orders Upgrades for its 4 E-767 AWACS

In May 2006, the Defense Security Cooperation Agency notified Congress of a possible Foreign Military Sale to Japan of four sets of Airborne Early Warning (AEW) and Command, Control and Communications (C3) mission equipment/Radar System Improvement Program (RSIP) Group A and B kits, plus spares and services to ensure complete AWACS mission equipment supportability, for subsequent installation and checkout in 4 previously procured E-767 Airborne Warning and Control Systems (AWACS) aircraft.

Boeing delivered the 4 AWACS E-767s to Japan between 1998-1999; they have been in service since 2000.
