ASALM (Advanced Strategic Air-Launched Missile)

[Yellow Palace]

Worth noting here that by the time the programme was cancelled, a missile from the SLAT/ASALM line was (by default) the front runner for the UK's SR(A).1244 Tactical Air-To-Surface missile. That version was called TIRRM - Tactical Integrated Rocket-Ramjet Missile - with an expected range of 520 to 700 km and an expected in-service date (in 1989) of 2001-2002.

Standard kerosene is not particularly dangerous, and is used for ship fuel anyways.

Weird kerosene might be of some concern, but there again if it had a particularly low flash point and high viscosity, probably not so much on the safety front. On the 'getting the damn missile to work properly in the Arctic' front, perhaps more so.
