The United States is to send Raytheon RTX AGM-154 Joint Stand-Off Weapon (JSOW) glide-bombs to Ukraine for use aboard its recently delivered Lockheed Martin F-16 Fighting Falcon combat aircraft.

US President Joe Biden made the announcement on 26 September during a visit of Ukrainian President Volodymyr Zelensky to the White House.

“To enhance Ukraine's long-range strike capabilities, I have decided to provide Ukraine with the Joint Standoff Weapon long-range munition,” President Biden said.

The baseline JSOW is a 1,000 lb-class glide-bomb with a maximum range of 116 km when released at high altitude and is already cleared for carriage on the F-16 of which Ukraine has received the first 10 of a pledged 79 jets (one was lost in late August).

The GPS/INS (inertial navigation system) and terminal imaging infrared-guided JSOW is available in four different variants – JSOW-A, JSOW-A1, JSOW-C, and JSOW-C1 – though it is not clear from Biden's announcement which is/are being transferred to Ukraine.
