A Guided Missile for $3-5k - Surely Some Mistake

When a Javelin costs £60k a pop read this and ask why arent we developing something similar

The Israeli's are also developing something similar, which confusingly, is called the Mini-Spike.

And even more confusingly, they also have a Spike missile - which bid and lost against the Javelin in the UK competition.

 

I think this was done before.

Surely this would be an answer to a cost cuting exercise. Light - total weight of about 5Kg (each projectile only weighs 2.5kg), cheap - launcher and projectile combined costs $10k and is fire and forget, it also has a range of 3.2Km.

Obviously we'd still retain the Javelin as the 'silver bullet' for tanks and heavily armoured vehicles but surely this would be ideal for lightly armoured vehicles and buildings
