Following in the footsteps of neighboring South Korea, Japan is considering the potential deployment
of the THAAD
system as they look to better protect themselves from North Korean nuclear threats. While no concrete plans are yet in place to deploy THAAD, military officials are looking at the option of beefing up defense capabilities and are “considering what can be done.” At present, Japan's missile defense system involves on ship-based SM-3 interceptors to target missiles in space and land-based PAC-3 batteries to intercept rockets flying closer to the ground. While this had been deemed sufficient measures, Pyongyang's increased ballistic missile testings have moved the procurement of a more long-range system onto the agenda.
THAAD: In flight
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, and land-based SM-3 programs will make it a direct THAAD competitor. So far, both programs remain underway.

Boeing is eager to sell
aerial refueling tanker to India. The Indian Air Force has yet to procure a capability to refuel its C-17 and P-8I aircraft, and New Delhi has eyed up the Pegasus to fill such a role. A laborious search has been underway to fill a six multi-role tanker capability soon to be vacated by their aging IL-76 aircraft. Earlier attempts to procure Airbus A 330 MRTT never came to fruition.
KC-135: Old as the hills…
DID’s FOCUS articles cover major weapons acquisition programs – and no program is more important to the USAF than its aerial tanker fleet renewal. In January 2007, the big question was whether there would be a competition for the USA’s KC-X proposal, covering 175 production aircraft and 4 test platforms. The total cost is now estimated at $52 billion, but America’s aerial tanker fleet demands new planes to replace its KC-135s, whose most recent new delivery was in 1965. Otherwise, unpredictable age or fatigue issues, like the ones that grounded its F-15A-D fighters in 2008, could ground its aerial tankers – and with them, a substantial slice of the USA’s total airpower.
KC-Y and KC-Z buys are supposed to follow in subsequent decades, in order to replace 530 (195 active; ANG 251; Reserve 84) active tankers, as well as the USAF’s 59 heavy KC-10 tankers that were delivered from 1979-1987. Then again, fiscal and demographic realities may mean that the 179 plane KC-X buy is “it” for the USAF. Either way, the KC-X stakes were huge for all concerned.
In the end, it was Team Boeing’s KC-767 NexGen/ KC-46A (767 derivative) vs. EADS North America’s KC-45A (Airbus KC-30/A330-200 derivative), both within the Pentagon and in the halls of Congress. The financial and employment stakes guaranteed a huge political fight no matter which side won. After Airbus won in 2008, that fight ended up sinking and restarting the entire program. Three years later, Boeing won the recompete. Now, they have to deliver their KC-46A.

Four companies have been awarded contracts by the US Navy to conduct risk reduction work on their designs for the MQ-25 Stingray. Boeing, General Atomics Aeronautical Systems and Lockheed Martin received contracts for $43 million each while Northrop Grumman received $35.8 million. The risk reduction work will see the companies alter previous designs of the MQ-25
as an unmanned strike bomber to fit its new role as an aerial tanker under the carrier-based air refueling system (CBARS
UCAS-D/ N-UCAS concept
The idea of UAVs with full stealth and combat capabilities has come a long way, quickly. Air forces around the world are pursuing R&D programs, but in the USA, progress is being led by the US Navy.
Their interest is well-founded. A May 2007 non-partisan report discussed the lengthening reach of ship-killers. Meanwhile, the US Navy’s carrier fleet sees its strike range shrinking to 1950s distances, and prepares for a future with fewer carrier air wings than operational carriers. Could UCAV/UCAS vehicles with longer ranges, and indefinite flight time limits via aerial refueling, solve these problems? Some people in the Navy seem to think that they might. Hence UCAS-D/ N-UCAS, which received a major push in the FY 2010 defense review. Now, Northrop Grumman is improving its X-47 UCAS-D under contract, even as emerging privately-developed options expand the Navy’s future choices as it works on its new RFP.

Raytheon and Kongsberg have successfully test-fired an extended range version
of Raytheon’s Advanced Medium-Range Air-to-Air Missile (AMRAAM
) from the National Advanced Surface-to-Air Missile System (NASAMS
). By simply pairing the sensor from the AMRAAM to an Evolved Sea Sparrow missile (ESSM
) the new variant gives a 50% in maximum range and 70% in maximum altitude. Modifications undertaken to accommodate the new missile include extending the top row of three canisters by a foot, and Raytheon is targeting first deliveries of the missile in the 2020 timeframe.

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.
