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.

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.

The JAS-39 Gripen: Sweden’s 4+ Generation Wild Card

As a neutral country with a long history of providing for its own defense against all comers, Sweden also has a long tradition of building excellent high-performance fighters with a distinctive look. From the long-serving Saab-35 Draken (“Dragon,” 1955-2005) to the Mach 2, canard-winged Saab-37 Viggen (“Thunderbolt,” 1971-2005), Swedish fighters have stressed short-field launch from dispersed/improvised air fields, world-class performance, and leading-edge design. This record of consistent project success is nothing short of amazing, especially for a country whose population over this period has ranged from 7-9 million people.

This is DID’s FOCUS Article for background, news, and contract awards related to the JAS-39 Gripen (“Griffon”), a canard-winged successor to the Viggen and one of the world’s first 4+ generation fighters. Gripen remains the only lightweight 4+ generation fighter type in service, its performance and operational economics are both world-class, and it has become one of the most recognized fighter aircraft on the planet. Unfortunately for its builders, that recognition has come from its appearance in Saab and Volvo TV commercials, rather than from hoped-for levels of military export success. With its 4+ generation competitors clustered in the $60-120+ million range vs. the Gripen’s claimed $40-60 million, is there a light at the end of the tunnel for Sweden’s lightweight fighter? In 2013 a win in Brazil started to answer that question.

The New Chinooks: Boeing’s Modern H-47 Heavy-Lift Helicopters

DII FOCUS articles offer in-depth, updated looks at significant military programs of record; this FOCUS Article covers the CH-47F/MH-47G Chinook helicopter programs, in the USA and abroad. These helicopters’ distinctive “flying banana” twin-rotor design stems from the brilliant work of aviation pioneer Frank Piasecki. It gives Chinooks the ability to adjust their positioning very precisely, while carrying a large airframe whose load capacity has made it the world’s most popular heavy-lift helicopter. The USA expects to be operating Chinooks in their heavy-lift role past 2030.

The CH-47F looks similar to earlier models, but offers a wide range of improvements in almost every aspect of design and performance. While the related HH-47’s $10-15 billion CSAR-X program win was terminated, delivery orders continue for CH-47Fs and for MH-47G Special Forces configuration helicopters. International orders or formal requests have also come in from Australia, Britain, Canada, Italy, the Netherlands, Turkey, and the UAE, with India and other countries expected to follow.

Saudi Snoops: RSAF Turns to King Airs

In recent wars, a lot of high tech gear has been upstaged by a surprising contender. Countries like the USA, Canada, Britain, Egypt, Iraq, and others are flying low-end turboprop business aircraft fitted with an array of sensors and a small crew. They’re cheap to buy, don’t use technology that makes export approval difficult, and are easy to maintain. Operating them is well within the capabilities of any country with an air force. Their sensors also offer more diversity and power than all but the highest-cost UAVs, in exchange for having just 1/2 to 1/3 of a high-end UAV’s mission endurance. No wonder many countries see them as a good complement to, or substitute for, existing UAV offerings.

Saudi Arabia has the money and clout to buy the expensive stuff. Nevertheless…

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…

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.

AH-64E Apache Block III: Evolving Battlefield Roles

The AH-64 Apache will remain the US Army’s primary armed helicopter for several more decades, thanks to the collapse of the RAH-66 Comanche program, and the retirement sans replacement of the US Army’s Armed Reconnaissance Helicopter (ARH). Apaches also serve with a number of American allies, some of whom have already expressed interest in upgrading or expanding their fleets.

The AH-64E Guardian Block III (AB3) is the helicopter’s next big step forward. It incorporates 26 key new-technology insertions that cover flight performance, maintenance costs, sensors & electronics, and even the ability to control UAVs as part of manned-unmanned teaming (MUT). In July 2006, Boeing and U.S. Army officials signed the initial development contract for Block III upgrades to the current and future Apache fleet, via a virtual signing ceremony. By November 2011, the 1st production helicopter had been delivered. So… how many helicopters will be modified under the AH-64 Block III program, what do these modifications include, how is the program structured, and what has been happening since that 2006 award? The short answer is: a lot, including export interest and sales.

Taiwan’s Force Modernization: The American Side

Despite China’s ominous military buildup across the strait, key weapons sales of P-3 maritime patrol aircraft, Patriot PAC-3 missiles, and diesel-electric submarines to Taiwan had been sabotaged by Taiwanese politics for years – in some cases, since 1997. The KMT party’s flip-flops and determined stalling tactics eventually created a crisis in US-Taiwan relations, which finally soured to the point that the USA refused a Taiwanese request for F-16C/D aircraft.

That seems to have brought things to a head. Most of the budget and political issues were eventually sorted out, and after a long delay, some major elements of Taiwan’s requested modernization program appear to be moving forward: P-3 maritime patrol aircraft, UH-60M helicopters, Patriot missile upgrades; and requests for AH-64D attack helicopters, E-2 Hawkeye AWACS planes, minehunting ships, and missiles for defense against aircraft, ships, and tanks. These are must-have capabilities when facing a Chinese government that has vowed to take the country by force, and which is building an extensive submarine fleet, a large array of ballistic missiles, an upgraded fighter fleet, and a number of amphibious-capable divisions. Chinese pressure continues to stall some of Taiwan’s most important upgrades, including diesel-electric submarines, and new American fighter jets. Meanwhile, other purchases from abroad continue.

Germany Upgrading Its CH-53G Helicopters

From 1971-1975, 110 “CH-53G Mittlerer Transporthubschrauber” derivatives of the CH-53D Sea Stallions were built in Germany. Though they share the CH-53E’s ability to lift medium-heavy loads, including up to 2 of Germany’s Wiesel armored infantry support vehicles, the CH-53Gs lack the 3rd engine and additional features of the improved CH-53E Super Stallions that have been operated by the US Marine Corps since 1981. A 2002 decision set a future force goal of 80 CH-53G and upgraded CH-53GS helicopters in the German Army, via modernization and life extension projects.

Which leads us to the current modernization project, even as Germany and France prepare their European Heavy-Lift Helicopter project for introduction around 2020. That effort is also surrounded by more urgent modifications, including one set that aims to create longer-range combat search and rescue capabilities:
