spread out to a degree. Another change was that the two tubes were now separately mounted, instead of sharing a common hinge, which allowed one to be lowered for reload while the other was still in firing position. Prototype problems During testing, the system proved to have a huge number of minor problems and continually failed. It was not until 1969 that the system was considered even partially usable and the missiles began to work reliably. A significant problem was due to the rocket smoke. In the original design, the concern had been that the smoke of previous weapon designs left a pointer directly back to the launcher which could then be attacked. Swingfire didn't need to be concerned about the smoke because the launcher itself would be hidden. However, in testing, it was found that the smoke was thick enough to obscure the missile or the target. This was especially a problem at long range when the missile was being viewed through the entire column of smoke. This made aiming at long range largely a matter of luck, and as a result the accuracy proved to be below specifications. The missile was initially presented to the Army for acceptance in July 1969. and on 28 July they initially rejected it until additional corrections were made. They also found the training systems were inadequate. The new owners of the system, British Aerospace, agreed to make several changes to the design, and the Army eventually accepted the design on a provision basis in August. FV102 Striker In 1960, the Army launched the Armored Vehicle Reconnaissance (AVR) program for a light tracked reconnaissance vehicle. The initial concept called for a single turret mounting both a gun and missiles, presumably Swingfire. However, attempts to design such a turret for a vehicle light enough for the requirements proved impossible and the project was cancelled in 1964. In its place, an even lighter aluminium armoured vehicle was designed, the Combat Vehicle Reconnaissance (Tracked), or CVR(T). This differed from AVR primarily in abandoning the single turret concept and using mission-specific turrets on different vehicles. The most widely produced version was the FV101 Scorpion which mounted the 76 mm L23A1 gun firing HESH rounds capable of destroying most armoured vehicles, but not main battle tanks. For this role, the FV102 Striker was designed, initially with a rotating turret mounting two Swingfire missiles on either side of the
