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.

The Saudis’ American Shopping Spree: F-15s, Helicopters & More

In October 2010, talks that Saudi Arabia was negotiating a $30-60 billion arms package with the USA were made official with a full multi-billion request that included 84 F-15 Strike Eagles to replace the Kingdom’s Tornado strike aircraft and/or F-15A-D fighters, upgrades for another 70 planes, about 132 UH-60 Black Hawk utility and AH-64 attack helicopters, and armaments to equip them.

This article looks at those requests, their tie-ins, the issues that are part of these potential deals, and related follow-on requests. As is often the case with DSCA announcements, years can pass between the requests and the signed contracts, but these contracts have started to roll in, alongside other significant buys.

US Hellfire Missile Orders, FY 2011-2020

Hellfire I/II missiles are the USA’s preferred aerial anti-armor missile, and are widely deployed with America’s allies. They equip America’s helicopter fleets (AH-64, AH-1, OH-58D, MH-60S/R), AH-64 and S-70 helicopters flown by its allies, and even Australia and France’s Eurocopter Tiger attack helicopters. Range is officially listed as 9 km/ 5.6 miles.

While Hellfires lack the fast-jet launch capabilities – and correspondingly extended maximum range – of the UK’s MBDA Brimstone missiles, Lockheed Martin’s missile has made big inroads as the world’s high-end helicopter-launched missile. It has also carved out unique niches as tripod-launched coastal defense assets, as the guided missile integrated into American UAVs like the MQ-1 Predator family, and even as a missile option for transport aircraft like the AC-208B Combat Caravan and C-130J/W Hercules.

The Wonders of Link 16 For Less: MIDS-LVTs

What one sees, all see. Jam-resistant Link-16 radios automatically exchange battlefield information – particularly locations of friendly and enemy aircraft, ships and ground forces – among themselves in a long-range, line-of-sight network. For example, air surveillance tracking data from an Airborne Warning and Control System (AWACS) aircraft can be instantly shared with fighter aircraft and air defense units. More than a dozen countries have installed Link 16 terminals on over 19 different land, sea, and air platforms, making it an interoperability success story.

While recent advancements may make AESA radars the future transmitters of choice, Link 16 is the current standard. The Multifunctional Information Distribution System-Low Volume Terminals (MIDS LVTs) were developed by a multinational consortium to provide Link 16 capability at a lower weight, volume, and cost than the Joint Tactical Information Distribution System (JTIDS). This free-to-view DID Spotlight article throws a spotlight on the program, explaining Link 16, and covering associated contracts around the world.

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.

Saudis Seek E-3 Fleet Upgrades

The 707-based E-3 aircraft forms the backbone of American, British, French, and NATO airborne early warning and control (AWACS), monitoring large swathes of airspace from an elevated position to detect incursions by enemy fighters, missiles, and even UAVs. When coupled with communications systems that allow it act as an airborne relay and command post for the aerial fight, it becomes a uniquely valuable weapons system. Under the 1981 – 1986 “Peace Sentinel” program, Saudi Arabia bought 5 E-3 AWACS(Airborne Early Warning and Control) planes and 8 KE-3A aerial tanker and cargo aircraft. Up to 3 of the KE-3s were later converted to RE-3A TASS(Tactical Airborne Surveillance System) electronic eavesdropping planes, leaving 5 E-3As, 3 RE-3As, and 5 KE-3 tankers.

Most E-3s around the world are well over 20 years old, and American, British, French, and NATO aircraft have received ongoing upgrades. Like Boeing’s US, British, French, and NATO customers, the Saudis are now seeking upgrades to keep their aircraft up to date. Broadly speaking, Saudi jets are getting 3 kinds of upgrades.

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…

2006 Saudi Shopping Spree: $2.9B to Upgrade Their M1 Tank Fleet

Saudi M1A2

In July 2006 the US DSCA informed Congress [PDF] that the government of Saudi Arabia wished to purchase 58 M1A1 Abrams tanks, then upgrade these M1A1s, along with its existing 315 M1A2s, to create 373 M1A2S (Saudi) Abrams configuration main battle tanks. The sale will include kits, 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 estimated cost is $2.9 billion.

This program also dovetails well with ongoing Cooperative Logistics Supply Support Agreement, which ensure support and spare parts for their American-made land equipment. This sale and upgrade program will be executed in 3 phases, and is well underway.

In 2003, Raytheon UK operation won the GBP 120 million pound contract to develop and produce Paveway IV, beating Boeing’s INS/GPS guided JDAM. The GPS/INS and laser-guided 500-pound bombs are a British project, and will add a number of other enhancements, including longer range than previous Paveway versions.

The British military had wanted to deploy Raytheon’s latest Paveway IV bombs in Afghanistan by September 2007, on board its newly-upgraded Harrier GR9 aircraft. Unfortunately, testing problems with Thales UK’s Aurora fuze removed that option. The MoD found a way to deploy the smart bombs with lesser capabilities by December 2007, and eventually deployed full Paveway IVs on its Harriers in Afghanistan. The weapon is now ready for use with its Tornado GR4 strike aircraft, which are replacing the Harriers, and has been qualified on the RAF’s Eurofighters.

Gulf States Requesting ABM-Capable Systems

Patriot PAC-2

It’s becoming clear that Gulf states, including Saudi Arabia, have stepped up their defense spending in recent years. Uncertainty creates perceptions of risk, and perceptions of risk lead to responses aimed at reducing that risk. That’s why arms spending is an incomplete but very concrete way of tracking a state’s real assessment of threats and priorities. Iraq is no longer a missile/WMD threat, but Iran’s ballistic missiles are another matter. They may be based on North Korean designs that lack accuracy, but the prospect of nuclear payloads is producing reactions.

Gulf states recognize that even a lucky conventional missile could wreak havoc if it hit key oil-related infrastructure, or damaged the larger and more nebulous target of business confidence. The spread of nuclear weapons would change the calculus completely. A 2007 US National Intelligence Assessment [redacted NIE summary, PDF] believed that Iran’s nuclear program had stopped, but others, including the United Nations and Israel, were more skeptical. By 2010, that skepticism had spread to US intelligence, which repudiated an assessment that seems set to join the infamous 1962 NIE of no Soviet missiles in Cuba [1].

The Gulf states’ response to these developments covers a range of equipment, but anti-ballistic missile capabilities appear to be rising to the top of the priority list.
