Ukraine's getting powerful long-range glide bombs from the US that will give its F-16s a new punch

• The US is sending Ukraine the Joint Standoff Weapon, an air-launched glide bomb.
• The powerful munition will give Ukraine's F-16s a new long-range weapon.
• Glide bombs have been heavily featured during the war, with Russia using them to devastating effect.

The US is sending Ukraine long-range glide bombs for its F-16 fighter jets, giving it new strike options.

President Joe Biden announced Thursday that he decided to provide Kyiv with the Joint Standoff Weapon to "enhance Ukraine's long-range strike capabilities" as part of a larger security assistance package.

The AGM-154 Joint Standoff Weapon (JSOW) is an air-launched glide bomb with a range of more than 70 miles that has been in service since the late 1990s. The bomb, which weighs over 1,000 pounds and has wings that pop out during flight, is used by the US Air Force, US Navy, and several other militaries.

There are multiple variants of the JSOW, but reports say Ukraine will be receiving the one with cluster munitions, which are small bomblets that disperse mid-flight, potentially causing more damage than a unitary warhead could.

The JSOW is compatible with the F-16s Ukraine received from NATO countries over the summer. The US has sent Kyiv air-to-surface and air-to-air munitions for the Amercan-made fourth-generation fighter jets.

The JSOW doesn't have the reach of some other long-range munitions that Ukraine has, like Storm Shadow/SCALP-EG cruise missiles provided by Britain and France, but its profile as a glide bomb will make it a useful asset for Kyiv.

A glide bomb is a type of stand-off munition, meaning an attacking aircraft can release it from a distance . Ukraine already has glide bombs in its arsenal , including some provided by France and the US, and has used these weapons to strike Russian positions.

The US-made JDAM has a much shorter range compared to the JSOW. The JSOWs will better allow Ukrainian F-16s to strike outside the range of Russian air defenses.

Russia also has glide bombs — some of which weigh over 6,000 pounds and have tremendous destructive capability — and has used them far more extensively to wreak havoc on Ukrainian civilians and troop positions.

Russia's glide bombs have been a constant headache for Ukraine this year. These munitions are nearly impossible to intercept , so the only way for Kyiv to defeat them is to either shoot down the attacking aircraft or destroy the planes on the ground at their bases.

Through the use of long-range drones, Ukraine has been targeting ammo depots and air bases.

Biden's JSOW disclosure was part of a larger announcement about new US security assistance to Ukraine that totals nearly $8 billion. Notably, this aid pasckage includes another high-profile Patriot air-defense battery and interceptor missiles.

Ukrainian President Volodymyr Zelenskyy, who is visiting the White House on Thursday, expressed gratitude for the new military aid, including the air-to-ground munitions.

"We will use this assistance in the most efficient and transparent manner to achieve our major common goal: victory for Ukraine, just and lasting peace, and transatlantic security," he said.
