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…

Latest updates[?]: #6 won't be the last - long-lead buy for ship #7; Keel laid for #5.
WMSL-750 Bertholf
The US Coast Guard’s massive $25 billion Deepwater meta-program (really Deepwater-II given post-9/11 changes) has endured more than its share of ups and downs. Nevertheless, Congressional support has remained strong, and efforts are being made to restructure the program and get it back on track. Yet the USCG’s Island Class cutter modification program, and the Deepwater Fast Response Cutter supposed to replace it, have faced many difficulties.
The Legend Class National Security Cutters are the largest ships in the Deepwater program, and represent the program’s flagship in more ways than one. The 418 foot, 4,400 ton ships will be frigate-sized vessels with a 21 foot draughts [1], and are rather larger than the 379 foot, 3,250 ton Hamilton Class High Endurance Cutters (HECs) they will replace. Controversies regarding durability and potential hull fatigue, as well as significant cost overruns, have shadowed the new cutter’s construction. rhe program has survived, and is pushing toward its end in a few years – but will the number of ships bought be enough to help the USCG? This DID FOCUS Article covers the Legend Class cutters’ specifications, program history, and key events.

Latest updates[?]: Radar ECP upgrade - and a radome upgrade, too.
AN/APG-79 AESA Radar
The AN/APG-79 Active Electronically Scanned Array (AESA) radar began life as a replacement. Initial F/A-18 E/F Super Hornet production batches installed Raytheon’s all-weather, multimode AN/APG-73, but the APG-79 has intrinsic technical features that offered revolutionary increases in capability, reliability, image resolution, and range.
Unlike the APG-73 that equipped the first Super Hornets, the APG-79′s AESA array is composed of numerous solid-state transmit and receive modules that are fixed in place, eliminating a common cause of breakdowns. To move their beams, they rely on electronic changes in each module’s transmissions, creating useful interference patterns in order to aim, focus and shape their output. Other system components include an advanced receiver/exciter, ruggedized commercial-off-the-shelf (COTS) processor, and power supplies. With its open systems architecture and compact COTS parts, it changes what both aircrews and maintenance staff can do with a fighter radar – and does so in a smaller, lighter package.

P-8A Poseidon
Maritime surveillance and patrol is becoming more and more important, but the USA’s P-3 Orion turboprop fleet is falling apart. The P-7 Long Range Air ASW (Anti-Submarine Warfare) Capable Aircraft program to create an improved P-3 began in 1988, but cost overruns, slow progress, and interest in opening the competition to commercial designs led to the P-7′s cancellation for default in 1990. The successor MMA program was begun in March 2000, and Boeing beat Lockheed’s “Orion 21″ with a P-8 design based on their ubiquitous 737 passenger jet. US Navy squadrons finally began taking P-8A Poseidon deliveries in 2012, but the long delays haven’t done their existing P-3 fleet any favors.
Filling the P-3 Orion’s shoes is no easy task. What missions will the new P-8A Poseidon face? What do we know about the platform, the project team, and ongoing developments? Will the P-3′s wide global adoption give its successor a comparable level of export opportunities? Australia and India have already signed on, but has the larger market shifted in the interim?

Latest updates[?]: Program timeline; Support contracts and an in-flight refueling study.
Northrop Grumman’s E-2C Hawkeye is a carrier-capable “mini-AWACS” aircraft, designed to give long-range warning of incoming aerial threats. 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 began replacing previous Hawkeye versions in 1973. They fly from USN and French carriers, from land bases in the militaries of Egypt, Japan, Mexico, and Taiwan; and in a drug interdiction role for the US Naval Reserve. 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.
