220 pounds of explosives is weak. The US SDB is about that and is rarely useful. 500 lbs is standard and that’s for the old MK82, onto which JDAM kits were attached.
As to adding guidance and mild propulsion to what is effectively an artillery shell, no big deal. Been done, by both sides, for years.
Russian tech is often superior, but this is not an example.
Now, what MAY be an example is the sheer availability of raw materials to make FAB3000 and 2000. Lots and lots of pounds of explosives. The US doesn’t have that. For over a year now the media’s obsession with drones has distracted from the reality that they can’t carry enough boomage to matter.
An artillery shell holds about 25lbs of explosive. An aerial bomb holds 8 times as much. And the range of this device is about 4x the shell. And it is precision guided, unlike most arty shells. For the discriminating artillery man, what’s not to like?
Are you aware that most of a bomb’s weight is in the casing, not the explosive filler?
Yeah right! A 155 artillery shell has 22 lbs of explosive. 1/10 a FAB 250. A precision guided 155 round cost $100,000 per. Raytheon has enough paid lobbyists to cover Congress. They don’t need you out here trying to bamboozle the FR rubes.
