This is a "Sparrowhawk" guided anti-aircraft missile. It is designed to be loaded into the "Sparrowhawk" AA Missile Rack.

The "Sparrowhawk" missile is an antique that never quite got out of the prototype stage. It was first tested in 2019, using then-revolutionary digital imaging technology to improve the old guidance technology of 'contrast seeking'. This technique uses an array of optical cameras mounted in the transparent fibreglass nose of the missile. The onboard computer looks for a spot in the image where the contrast changes the fastest, and then attempts to keep that spot dead centre in front of it. This system has been employed mostly in air-to-ground missiles due to the greater effectiveness of other guidance systems against Earth-built aircraft.

The Sparrowhawk program was cancelled only months before the design would've been put into service. It was ready to be put into service then, and it's ready now. We've revived the Sparrowhawk AA program and the UN has agreed to put it into mass production.

The "Sparrowhawk" is mounted in 7-missile racks, which can then be mounted to the appropriate weapons hardpoints on our aircraft. The missile's range is far superior to any of the other weapons we have available at this time; it's effective out to twelve kilometres from the aircraft thanks to its unique guidance technology. It's also hardened against EMP to prevent it from being disabled electronically.

The individual missiles weigh approximately 65 kilos. A fully-loaded rack is approximately 600 kilos.

Recommended Doctrine

The Sparrowhawk should be an essential part of our aerial defence plan. Preferably all our interceptors would be carrying at least one full rack at launch. The ability to soften up an enemy while we close in is something not to be ignored lightly. Overall accuracy will be poor -- we estimate approximately one hit in twelve -- but the range difference is one of miles.

Compared to the TR-20 rocket pod, the Sparrowhawk's effective range is greater by eight kilometres. Compared the SHIVA cannon, it's greater by ten kilometres. While these deliver a lot more damage than the Sparrowhawk at their respective ranges, the closer we have to get to attack the enemy, the greater the danger to our pilots and interceptors.

It should theoretically be possible to simply overwhelm UFOs with Sparrowhawk fire if we could field enough aircraft armed with them. However, our Director of Finances has expressed her extreme displeasure with this idea, and I have to admit she's got a point -- but I think it's something we should keep in mind if we come up against a particularly dangerous UFO that needs to be taken out at range and as quickly as possible.
