Ukrainian pilots rise Soviet jets to new heights with Western munitions

Defense Express reports.

The Air Force Communications Directorate of Ukraine's Armed Forces released a video interview featuring a Su-27 pilot, call sign Viking, serving with the 39th Tactical Aviation Brigade.

The interview reveals key insights into adapting Western guided munitions for Soviet-era aircraft. For instance, the Small Diameter Bomb (SDB) can be released from distances potentially exceeding those of the JDAM-ER, due to its aerodynamic design. Verified data suggests the JDAM-ER's range is about 40 kilometers, indicating SDB might surpass this. Each Su-27 can carry up to eight SDBs, with mission frequency depending on steady supply chains from Ukraine's partners.

Regarding AGM-88 HARM missiles, their early use achieved 90% effectiveness against Russian air defenses. Now, they primarily suppress air defenses during combined strikes.

Western bombs are also notably more accurate, with an 85% hit rate compared to 20% for Russian FABs equipped with UMPC modules. However, Russian guided bomb usage remains higher in volume.

The interview highlights how rapidly air combat conditions evolve, noting that even a two-week break can require pilots to relearn operational scenarios from scratch.
