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.

Adding Arleigh Burkes: H.I.I. Steps Forward for DDG-51 Restart

In April 2009 Bath and Ingalls agreed to the Navy’s surface combatant plans, thus heralding a significant restructuring within the American naval shipbuilding community. Under the agreements, the USA would end production at 3 Graf Spee sized DDG-1000 Zumwalt Class “destroyers,” but shift all production from the Congressionally-mandated joint arrangements to General Dynamics Bath Iron Works in Maine, which had already made program-related investments in advanced shipbuilding technologies.

Northrop Grumman (now Huntington Ingalls Industries) would retain its DDG-1000 deckhouse work, but their main exchange was additional orders for DDG-51 Arleigh Burke Class destroyers. Their Ingalls yard in Pascagoula, Mississippi would continue building the DDG-51 destroyers, beginning with 2 ordered in FY 2010-2011.

LCS: The USA’s Littoral Combat Ships

Exploit simplicity, numbers, the pace of technology development in electronics and robotics, and fast reconfiguration. That was the US Navy’s idea for the low-end backbone of its future surface combatant fleet. Inspired by successful experiments like Denmark’s Standard Flex ships, the US Navy’s $35+ billion “Littoral Combat Ship” program was intended to create a new generation of affordable surface combatants that could operate in dangerous shallow and near-shore environments, while remaining affordable and capable throughout their lifetimes.

It hasn’t worked that way. In practice, the Navy hasn’t been able to reconcile what they wanted with the capabilities needed to perform primary naval missions, or with what could be delivered for the sums available. The LCS program has changed its fundamental acquisition plan 4 times since 2005, and canceled contracts with both competing teams during this period, without escaping any of its fundamental issues. Now, the program looks set to end early. This public-access FOCUS article offer a wealth of research material, alongside looks at the LCS program’s designs, industry teams procurement plans, military controversies, budgets and contracts.

Soldier Battle JTRS: The HMS Radio Set + SANR

The Pentagon’s JTRS (Joint Tactical Radio System) aimed to replace existing radios in the American military with a single set of software-define radios that could have new frequencies and modes (“waveforms”) added via upload, instead of requiring multiple radio types in ground vehicles, and using circuit board swaps in order to upgrade. Trying to solve that set of problems across the entire American military meant taking on a very a big problem. Maybe too big. JTRS has seen cost overruns and full program restructurings, along with cancellation of some parts of the program.

JTRS HMS (Handheld, Manpack & Small Form-Fit) radios, for use by the individual solder, have survived the tumult, and are now headed into production. They offer soldiers more than just improved communications, and have performed in exercises and on the front lines. Now, production is ramping up.

Missile Envy: Modernizing the US ICBM Force

For 50 years, land-based Intercontinental Ballistic Missiles (ICBMs) have been part of the US primary strategic deterrence capability, the nuclear-armed triad that also includes submarine-launched ballistic missiles and long range heavy bombers.

Although the main target for the US deterrent – the Soviet Union – imploded in 1991, other threats – such as nuclear-armed rogue states and non-state actors – have emerged. To address these new threats, the US Air Force undertook a major ICBM modernization program.

To carry out this program, the USAF awarded a 15-year ICBM Prime Integration Contract (F42610-98-C-0001) in 1997 to a team led by Northrop Grumman. Since then, the team, which includes Lockheed Martin, Boeing, and ATK, has been carrying out a major modernization of the ICBM system to ensure its readiness.

Eurofighter’s Future: Tranche 3, and Beyond

The multi-national Eurofighter Typhoon has been described as the aerodynamic apotheosis of lessons learned from the twin engine “teen series” fighters that began with the F-14 and F-15, continued with the emergence of the F/A-18 Hornet, and extended through to the most recent F/A-18 Super Hornet variants. Aerodynamically, it’s a half generation ahead of all of these examples, and planned evolutions will place the Eurofighter near or beyond parity in electronic systems and weapons.

The 1998 production agreement among its 4 member countries involved 620 aircraft, built with progressively improved capabilities over 3 contract “tranches”. By the end of Tranche 2, however, welfare state programs and debt burdens had made it difficult to afford the 236 fighters remaining in the 4-nation Eurofighter agreement. A 2009 compromise was found in the EUR 9 billion “Tranche 3A” buy, and the program has renewed its efforts to secure serious export sales. Their success will affect the platform’s production line in the near term, and its modernization plans beyond that.

The C-130J: New Hercules & Old Bottlenecks

The C-130 Hercules remains one of the longest-running aerospace manufacturing programs of all time. Since 1956, over 40 models and variants have served as the tactical airlift backbone for over 50 nations. The C-130J looks similar, but the number of changes almost makes it a new aircraft. Those changes also created issues; the program has been the focus of a great deal of controversy in America – and even of a full program restructuring in 2006. Some early concerns from critics were put to rest when the C-130J demonstrated in-theater performance on the front lines that was a major improvement over its C-130E/H predecessors. A valid follow-on question might be: does it break the bottleneck limitations that have hobbled a number of multi-billion dollar US Army vehicle development programs?

C-130J customers now include Australia, Britain, Canada, Denmark, India, Israel, Iraq, Italy, Kuwait, Norway, Oman, Qatar, Saudi Arabia, South Korea, Tunisia, and the United States. American C-130J purchases are taking place under both annual budgets and supplemental wartime funding, in order to replace tactical transport and special forces fleets that are flying old aircraft and in dire need of major repairs. This DID FOCUS Article describes the C-130J, examines the bottleneck issue, covers global developments for the C-130J program, and looks at present and emerging competitors.

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.

UAE Buys Saab’s Erieye AEW&C Aircraft

In November 2009, Saab announced a 1.5 billion SEK (about $220 million) contract from the United Arab Emirates for 2 of its Saab 340 regional turboprops, equipped with Erieye active-array radars that can scan large airspace volumes, and with related command and control systems. The Saab 340 AEW contract also includes ground equipment, initial spares, and support services.

The UAE is just the latest buyer of Saab’s Erieye system.

AMRAAM: Deploying & Developing America’s Medium-Range Air-Air Missile

Raytheon’s AIM-120 Advanced, Medium-Range Air to Air Missile (AMRAAM) has become the world market leader for medium range air-to-air missiles, and is also beginning to make inroads within land-based defense systems. It was designed with the lessons of Vietnam in mind, and of local air combat exercises like ACEVAL and Red Flag. This DID FOCUS article covers successive generations of AMRAAM missiles, international contracts and key events from 2006 onward, and even some of its emerging competitors.

One of the key lessons learned from Vietnam was that a fighter would be likely to encounter multiple enemies, and would need to launch and guide several missiles at once in order to ensure its survival. This had not been possible with the AIM-7 Sparrow, a “semi-active radar homing” missile that required a constant radar lock on one target. To make matters worse, enemy fighters were capable of launching missiles of their own. Pilots who weren’t free to maneuver after launch would often be forced to “break lock,” or be killed – sometimes even by a short-range missile fired during the last phases of their enemy’s approach. Since fighters that could carry radar-guided missiles like the AIM-7 tended to be larger and more expensive, and the Soviets were known to have far more fighters overall, this was not a good trade.
