They put a K in where they shouldn't have.... 5,000m is the range, not 5,000km which would make it an ICBM...
Having IR guided missiles like this is useful as they are essentially fire and forget, but the new Pine SAMs based on the SOSNA missiles are just so much better.
The first models are laser beam riding, which means anything the launcher can see and track can be engaged, and their flight speed is enormous so they get to 10km targets in about 10 seconds or so... this is outstanding because it means in 15 seconds you are ready to engage the next target even out to max range, but much of the time the target will be a 5-6km range so 10 seconds later you can find your next target and engage.
Laser beam riding missiles against air targets you can lase the target to get a precise range and closing speed so the laser beam the missile flys down can be pointed 20m above the target till it gets within 1km of the target so the target wont even know it is being engaged till about a second before impact and chaff and flares and DIRCMs wont help because the missile is looking for the laser beam back at the launcher, not reflecting off the target.
IR guided missiles are very useful too and should be able to be fired on the move if needed, but then so should Pine.
Both systems are excellent for low emission use and sneaky attacks and while its range is only 5km, the Strela-1MN with a significant warhead would be very useful against higher flying bigger targets too.
