The US State Department has approved a potential sale of 1,532 Joint Direct Attack Munition-Extended Range (JDAM-ER) kits to Ukraine, with a total estimated value of $373.6 mn, according to an official notice issued on 5 May 2026.
Ukrainian defense outlet Militarnyi reports that Ukraine requested 1,200 kits for JDAM KMU-572 munitions and 332 kits for JDAM KMU-556 munitions. The kits convert unguided gravity bombs into precision-guided weapons.
Reuters reports that the principal contractor will be Boeing Company.
What the package includes
Beyond the conversion kits, the deal covers FMU-139 fuzes, JDAM technical support equipment, spare parts, consumables, accessories, repair and restoration services, software, and related hardware, according to Militarnyi.
The agreement also includes the transfer of classified and unclassified technical documentation, transportation support, studies and assessments, and engineering, technical, and logistical services provided by the US government and contractors, the outlet reports.
State Department rationale
The State Department, as paraphrased by Militarnyi, said the sale would support US foreign policy goals and national security objectives by strengthening the defense capabilities of a partner country that plays an important role in political stability and economic development in Europe.
How JDAM-ER works
The JDAM kit converts conventional aerial bombs into high-precision weapons fitted with an inertial navigation system and a GPS receiver, Militarnyi reports.
The kit consists of folding wings attached mid-body, which extend flight range, and a tail module containing steerable fins along with the navigation and electronic equipment that corrects the bomb's trajectory in flight.
Activation begins before release: the carrier aircraft transmits its coordinates, speed, and flight parameters to the munition. After separation, the bomb autonomously flies to the designated coordinates, which can be loaded before takeoff, corrected by the crew in flight, or transmitted via onboard targeting systems, according to the outlet.
The trajectory is programmed for an optimal impact angle, which Militarnyi reports improves effectiveness against fortified targets and partially reduces exposure to air defenses.
Ukraine mainly uses the JDAM-ER variant, which has an extended range of up to 72.4 km.
