its newest AMRAAM-ER air-to-air missile will have extended range and more maneuverability. It plans tests before the year is out.

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.

Maj. Gen. Michael Lundy, the Army's aviation chief, indicated that in facing two competing technologies from two vendors for the medium-capacity variant of the Future Vertical Lift program, the Army would like both. One can be fitted for the troop carrying role, and the other for the attack/reconnaissance role. The Bell V-280 Valor (tilt rotor) has been theoretically competing against the Sikorsky/Boeing SB>1Defiant. Lundy told BreakingDefense.com
that the decision was akin to the split between the Apache versus the Black Hawk.
The plan depends on the assumption
- that other services have not been quite as bold in making - that sequestration will be lifted for FY 2016 onward. Lundy's tone was fatalistic, indicating that the Army was planning for that one rosy scenario because the others - however likely - wouldn't suit: "If we went to the worst case, it would affect almost every modernization program we’ve got in our branch."
In addition to vanquishing sequestration, the Army's modernization plans hinge on Congress approving their ARI plan, which involves shelving Kiowas and replacing that reconnaissance capacity with Apaches taken from reserve units, among other decisions that would be unpopular in many individual congressional districts.
The future is now
The JMR-TD program is the science and technology precursor to the Department of Defense’s estimated $100 billion Future Vertical Lift program, which is expected to replace between 2,000-4,000 medium class UH-60 utility and AH-64 attack helicopters after 2030.
In reality, FVL will fall far short of that number if it ever goes ahead, but those figures are the current official fantasy. While they’re at it, the Pentagon wants breakthrough performance that includes the same hovering capability as smaller armed scout helicopters, and a 100+ knot improvement in cruising speed to 230+ knots. That’s almost certainly achievable, thanks to new developments that involve very different helicopter designs.

Latest updates[?]: COBRA Block I order.
MH-53E & Mk-105 sled
The US Navy currently uses large CH-53/MH-53 helicopters and towed sleds to help with mine clearance work, but they hope to replace those old systems with something smaller and newer. The MH-60S helicopter’s Airborne Mine Counter-Measures (AMCM) system adds an operator’s station to the helicopter cabin, additional internal fuel stores, and towing capability, accompanied by a suite of carried systems that can be mixed and matched. AMCM is actually 5 different air, surface and sub-surface mine countermeasures systems, all deployed and integrated together in the helicopter.
While the US Navy develops AMCM, and complementary ship-launched systems for use on the new Littoral Combat Ships, new minehunter ship classes like the Ospreys are being retired by the US Navy and sold. All in an era where the threat of mines is arguably rising, along with tensions around key chokepoints like the Suez Canal and Strait of Hormuz.
This article explains the components involved (AQS-20, ALMDS, AMNS, OASIS, RAMICS; COBRA, RMS, SMCM), chronicles their progress through reports and contracts, and provides additional links for research.

Latest updates[?]: Multinational order for missiles and spares; Loss in India.
The FGM-148 Javelin missile system aimed to solve 2 key problems experienced by American forces. One was a series of disastrous experiences in Vietnam, trying to use 66mm M72 LAW rockets against old Soviet tanks. A number of replacement options like the Mk 153 SMAW and the AT4/M136 spun out of that effort in the 1980s, but it wasn’t until electronics had miniaturized for several more cycles that it became possible to solve the next big problem: the need for soldiers to remain exposed to enemy fire while guiding anti-tank missiles to their targets.
Javelin solves both of those problems at once, offering a heavy fire-and-forget missile that will reliably destroy any enemy armored vehicle, and many fortifications as well. While armored threats are less pressing these days, the need to destroy fortified outposts and rooms in buildings remains. Indeed, one of the lessons from both sides of the 2006 war in Lebanon has been the infantry’s use of guided missiles as a form of precision artillery fire. Javelin isn’t an ideal candidate for that latter role, due to its high cost-per-unit; nevertheless, it has often been used this way. Its performance in Iraq has revealed a clear niche on both low and high intensity battlefields, and led to rising popularity with American and international clients.
