On August 17, the Ukrainian military test fired its indigenously developed Neptun cruise missile, striking a sea target from 100 km. Neptun, a long-range, subsonic antiship cruise missile, reportedly has ground-, sea-, and air-launched variants. The missile also has capability against land targets and bears visual similarity to the Russian Kh-35. The cruise missile was previously flight tested in January 2018. According to a Ukrainian defense expert Serhiy Sguretz, Neptun can cruise at altitudes between 10 and 30 m before diving for terminal impact at 4 to 5 m. Its maximum range is between 280 km and 300 km.
