From CNN: U.S is sending Patriot missiles and JDAM kits to Ukraine in the new weapons package. The JDAM units will turn Ukraine's stock pile of dumb bombs into GPS guided munitions that can be launched from planes with a 28km range
Thats a maximum of 28km range, which requires high altitude and high speed. A more realistic range for the altitude that the UAF currently fly at to stay alive is <12km per JDAM so quite short range but a nice "cheap" precision weapon in plentiful numbers.
IIrc they bolt onto standard dumb bombs of all sorts, depending on the package I think it just requires a laser designator or GPS coordinates to be preloaded. I think they've been retrofitted to loads of aircraft as it was a cheap way to updated Korean war era stuff to be more effective, both the aircraft and hundreds of thousands of bombs during Vietnam etc
Thats the issue that will slow their usage down slightly, integration in the aircraft, because even the simplest of dumb bombs need (for modern aircraft) wiring and software adding to the aircraft to allow those bombs to be fused, armed and fed release signals, usually from a specialised computer (SMS for example). NATO uses a set MIL-STD-1760 set of connections, which the UAF doesn't have on any of their aircraft, so those will need modifying, probably along the lines of the adaption of the LAU-118 HARM launchers the UAF is already using.
So now we've either got a Soviet bomb with a US JDAM kit kludged onto it or, and I think this is more probable, the US has given/will give the UAF a bunch of the Mk80 series bombs which the JDAM kit is designed for so now all thats left is the wiring needed to hook up the wiring for arm, fuse and release and away they go and a a stand-alone SMS system for them and "hope" that they release smoothly for the launch aircraft.
Any target co-ordinates can, like the HARM, be pre-programmed into the weapon manually before the launch aircraft takes off, which makes them useless for rapid;ly moving targets like Shoot & Scoot artillery etc but ideal for things like HQ's, supply depots etc, with the disadvantage that the low release altitude means the launch aircraft has to be closer to the defended targets.
