A UV Missile Approach Warning System (MAWS) should be able to detect which of the following missiles during the boost phase?

The correct answer encompasses the ability of a UV Missile Approach Warning System (MAWS) to detect various types of missiles, particularly during their boost phase. A UV MAWS is designed to pick up on the infrared signatures produced by missiles when they are actively thrusting—this is especially relevant during the boost phase when the missile's engine is firing and generating a significant amount of heat.

In the case of each missile type listed: the RADAR-guided SA-2 missile, the LASER-guided ADATS missile, and the infrared-guided Stinger missile, their operational characteristics mean they all can produce infrared signatures during their boost phase.

The SA-2 missile, despite being primarily radar-guided, still generates heat and can thus be detected by infrared sensors in its initial phase of flight. The ADATS missile, while it uses a laser guidance system, also creates a thermal signature upon launch due to its propulsion system. Similarly, the Stinger missile, which is infrared-guided, is designed to be highly detectable by IR systems both when it is launched and in its climb phase.

Therefore, the UV MAWS should be capable of detecting all of these missile types during their boost phase, making “All of the above” the correct answer
