AIM-120C from F-22A

AMRAAM was designed with the lessons of Vietnam in mind, and of local air combat exercises like ACEVAL and Red Flag.

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 which required a constant radar lock on one target. In addition, 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.

Enter AMRAAM – the AIM-120 Advanced, Medium-Range Air to Air Missile. This focus article covers successive generations of AMRAAM missiles, international contracts and key events from 2006 onward, and even some of its emerging competitors. New materials will be highlighted in green type. The most recent additions involve an order for Greece, and changes to the guidance unit…

LHA-R Concept
(click to view full)

Modern U.S. Navy Amphibious Assault Ships project power and maintain presence by serving as the cornerstone of the Amphibious Readiness Group (ARG) / Expeditionary Strike Group (ESG). A key element of the Seapower 21 doctrine pillars of Sea Strike and Sea Basing, these LHA/LHD ships transport, launch, and land elements of the Marine Expeditionary Brigade (MEB) via a combination of LCAC hovercraft, amphibious transports and vehicles, helicopters, and aircraft.

Designed to project power and maintain presence, LHA-Replacement (LHA-R, aka. LH-X and now the America Class) large deck amphibious assault ships will replace the LHA-1 Tarawa Class. They’re based on the more modern LHD Wasp Class design, but remove the LHD’s landing craft and well deck. The end product is essentially a revival of the World War 2 escort carrier concept, with integrated berthing, cargo, and light vehicle spaces for Marines. LHA-R ships will be almost 80 feet longer than USS Wasp and 10 feet wider, since they don’t have to fit through the Panama Canal. As a result, these ships will weigh in at 50,000 tons/ 45,700t fully loaded rather than 42,400t full load for LHD 8. Though DID uses the term “escort carriers” due to the size of their aerial complement, note that their overall displacement will be larger than France’s 43,000t FNS Charles De Gaulle nuclear powered aircraft carrier.

Patriot PAC-2

A 2007 US National Intelligence Assessment [redacted NIE summary] believes Iran’s nuclear program has stopped, but others, including the United Nations and Israel are more skeptical. Intelligence is always a very uncertain and ambiguous exercise, and occasionally features assessments like the somewhat infamous NIE whose 1962 judgment was that there were no Soviet missiles in Cuba¹. Uncertainty creates perceptions of risk, and perceptions of risk lead to behaviors aimed at reducing that risk. Iraq is no longer a missile/WMD threat, Iran’s regular and Revolutionary Guards air forces remain relatively weak, and Iran’s ballistic missiles based on North Korean designs lack accuracy. Still, even a lucky conventional missile could create issues in some Gulf states if it hit important oil-related infrastructure, or hit the larger and more nebulous target of business confidence.

Arms spending is an incomplete but very concrete way of tracking a state’s real assessment of threats and priorities. It’s becoming clear that Gulf states, including Saudi Arabia, have stepped up their defense spending in recent years. Those expenditures cover a range of equipment, but anti-ballistic missile capabilities appear to be rising to the top of the priority list. Now over $10 billion worth of December 2007 Patriot missile upgrade requests in the UAE and Kuwait are shining a spotlight on the region’s new defense priorities. Some of those reqests are now becoming contracts…

Northrop Grumman’s E-2C Hawkeye began replacing previous Hawkeye versions in 1973, and serves as the US Navy and French Navy’s carrier-capable “mini-AWACS” aircraft. Its primary role is advance warning of incoming aerial threats; ship-based radars are far larger and more powerful, but cannot scan below the angle of the horizon. 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 also fly from land bases in the militaries of Egypt, Japan, Mexico, Singapore, and Taiwan; and in the US Naval Reserve in a drug interdiction role. 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. This DID FOCUS Article covers the E-2D program, from the new platform and its capabilities to the budgets, contracts, and companies making it all fly. The latest news includes a pair of contracts aimed at getting the first E-2Ds ready, and an associated engine contract…

THAAD: In flight
(click to view full)

The Terminal High Altitude Area Defense (THAAD) system is a long-range, land-based theater defense weapon that acts as the upper tier of a basic 2-tiered defense against ballistic missiles. It’s designed to intercept missiles during late mid-course or final stage flight, flying at high altitudes within and even outside the atmosphere. This allows it to provide broad area coverage against threats to critical assets such as population centers and industrial resources as well as military forces, hence its previous “theater (of operations) high altitude area defense” designation.

This capability makes THAAD different from a Patriot PAC-3 or the future MEADS system, which are point defense options with limited range that are designed to hit a missile or warhead just before impact. The SM-3 Standard missile is a far better comparison, but the SM-3 is a naval counterpart and could offer positioning advantages or disadvantages depending on the area to be defended. A multi-layered anti-ballistic missile system should ideally have both land and naval options, as well as theater-level and point defenses backed by a 3rd tier of longer ranged midcourse-defense missiles (q.v. GBI) and/or space-based weapons that can hit the missile during its boost phase.

This is DID’s FOCUS article covering the THAAD system, and newer items will be indicated in green type as a reader convenience. The latest news includes another successful intercept test…

EA-6B Prowler
(click to view full)

With the retirement of the US Air Force’s long-range EF-111 Raven “Spark ‘Vark,” the aging 4-seat EA-6B Prowlers are now the USA’s sole remaining tactical aircraft type for radar jamming, communications jamming and information operations like signals interception. They’ve been predictably busy as a result. In Iraq, they’ve been used for everything from escorting strike aircraft against heavily defended targets during the opening days of the war, to disrupting enemy IED attacks by jamming all radio signals in an area.

All airframes have lifespan limits, however, and the EA-6B is no exception. The aircraft’s 50 year old airframe design is also something of a mixed blessing. It offers excellent range, carrying capacity, and efficient subsonic performance – at the expense of poor self-defense capabilities, and difficulty keeping up with friendly aircraft traveling at high subsonic speeds.

EA-18G at Pax
(click to view full)

By 2009, therefore, a new electronic warfare aircraft is scheduled to make its appearance – one based on a new airframe, with strong self-defense capabilities as well as electronic attack potential. The EA-18G Growler is based on Boeing’s 2-seat F/A-18F Super Hornet multi-role fighter (which traces its history from the Northrop YF-17 and McDonnell Douglas F-18) and has 90% commonality, just as its predecessor the EA-6B was based on Grumman’s robust A-6 Intruder attack aircraft. At present, it is slated to be the only dedicated electronic warfare aircraft in the USA’s future force – and since the USA is the only western country with such aircraft, the EA-18G would be the sole source of tactical jamming support for NATO air forces as a whole.

This is DID’s focus article for the USA’s EA-18G Program, describing the aircraft and key systems, outlining the program, and keeping track of ongoing developments, contracts, et. al. that affect the program. New items will be highlighted via green type. The latest item is a spares contract…

SM-2 Launch w. AEGIS
(click to view full)

Variants of the SM-2 Standard missile are the USA’s primary fleet defense anti-air weapon, and in service with 13 navies worldwide. The most common variant is the RIM-66K-L/ SM-2 Standard Block IIIB, which entered service in 1998. It includes a number of modifications over previous versions, including greater capability at even lower altitudes, a more powerful fragmentation warhead, and a side-mounted infrared seeker developed in the Missile Homing Improvement Program (MHIP) to supplement the missile’s semi-active radar guidance system. These missiles work best when paired with the AEGIS radar and combat system, but can be employed independently.

DID details Raytheon’s recent US contracts related to the Standard Missile family from April 2006 onward, and also adds some budgetary and technical background that can help put them in context. New material is indicated in green type. The latest news involves a successful ABM test intercept – this time, by an SM-2 Block IV; and the first test of the forthcoming SM-6…

M777: dragon’s breath
(click to view full)

The M777 ultra-lightweight towed 155mm howitzer has an integrated digital fire control system, and can fire all existing 155mm projectiles. Nothing new there. What is new is the fact that this 9,700 pound howitzer saves over 6,000 pounds of weight by making extensive use of titanium and advanced aluminum alloys, allowing it to be carried by Marine Corps MV-22 tilt-rotor aircraft or medium helicopters, and/or airdropped by C-130 aircraft. The new gun is a joint program between the US Army and Marine Corps to replace existing 155mm M198s, and will perform fire support for U.S. Marine Air Ground Task Forces and U.S. Army Stryker Brigade Combat Teams.

Britain is also an M777 LWH development partner, but Canada became the first country to field it in combat via an emergency buy before their 2006 “Operation Archer” deployment to Afghanistan. This is is DID’s new FOCUS article covering the M777 program. The latest news is a follow-on order from Canada…

Raytheon Facility-100% Integrated Air Defense Center in Andover, MA received the contract (FA8807-08-D-0002)

Mk-44 firing RAM
(click to view full)

The Rolling Airframe Missile (RAM) MK-31 guided missile weapon system is co-developed and co-produced under a NATO cooperative program between the United States and German governments to provide a small, all-weather, low-cost self-defense system against aircraft and cruise missiles. The RIM-116 was later called RAM (Rolling Airframe Missile), because it spins during flight. To save costs, Designation Systems notes that the RAM was designed to use several existing components, including the rocket motor of the MIM-72 Chaparral, the warhead of the AIM-9 Sidewinder and the IR seeker of the FIM-92 Stinger. Cueing is provided by the ship’s ESM suite or radar.

RAM is currently installed, or planned for installation, on 78 U.S. Navy and 30 German Navy ships, including American LSD, LHD, LPD and CVN ship types. This number will grow as vessels of the LPD-17 San Antonio Class and Littoral Combat Ships enter the fleet, and the LCS will sport an upgraded SeaRAM system that will include its own integrated radar and IR sensors. The Korean Navy has also adopted RAM for its KDX-II and KDX-III destroyers, and its LPX Dokdo Class amphibious assault ships; other navies using or buying RAM include Egypt, Greece, and the UAE/Dubai.
