"With unguided munitions, a toss/lofted technique significantly reduces accuracy. Hammer and [U.S.-supplied unpowered] JDAM-ER [glide-bombs] both come standard with GPS-assisted inertial navigation system (INS) guidance packages that would allow them to zero in on set coordinates even when employed indirectly.”

"Much more importantly, the French precision-guided munitions have the REK [Range Extension Kit tail unit], which is a solid-fuel rocket booster designed to extend the weapon’s range. This is already a very useful additional capability when employing these weapons in level flight at higher altitudes, giving 500-pound/250-kilogram class versions the ability to hit targets up to 43 miles (70 kilometers) away. That is similar to the stated maximum range of the unpowered JDAM-ER with its pop-out wing kit.”

The whole point of having these guided bombs is that you can wildly roll away as soon as you achieve the correct range to target, and you would want to bail out of the combat zone as soon as possible because the entire combat zone is likely filled with enemy anti air assets that can kill you, and you want to get out of their range as quickly as you can.

They are GPS assisted, internally (self) navigating, rocket assisted bombs.

What that means is, you have already set the GPS location you want to hit, you loose the bombs and get the hell out asap, the rocket fires and the fins on the bomb actuate so as to generate a flight/glide path for the bomb that will guide it to the target.

Basically, its much more akin to a short range, air to ground missile than it is to a 'dumb' unguided bomb.

The difference being that the rocket on this is used to fly the bomb upwards, to gain altitude and thus range, then it glides downward toward the target, as opposed to a more conventional air to ground missile that would not have a glide stage and would be doing powered flight the whole time.

That, and these kinds of things are a hell of a lot cheaper than actual missiles, so you can get and use more of them.

The other engineering achievement of these things is the pylon, which interfaces between the russian-designed target designation systems on board the russian-designed aircraft, and translates this into being able to GPS program the specific target coordinates of the NATO-designed guided bombs before they are loosed.

An extremely oversimplified metaphor here would be that if you have American appliances or gadgets, you're going to need an adapter to charge/power them if you take them to another country with different power sockets and standard voltages.

In general, this is what is called a stand-off munition, which is a custom designed or modified version of a weapon that allows you to accurately hit targets from a range outside the ability of the enemy to smack back at you.
