 Russia had five S-400 air defense batteries in Crimea, Ukraine blew up too. In the years prior to its wider war on Ukraine, the Russian Air Force deployed five batteries of its best S-400 surface-to-air missiles plus their radars to occupy Crimea. Forbes media outlet wrote this. It is noted that in less than a month the Ukrainian navy has destroyed two of them. Every S-400 battery the Ukrainians knock out is one fewer S-400 battery defending the Russian Black Sea Fleet at its anchorage in Sevastopol. The first raid on the S-400 on August 23rd targeted the battery in Cape Tarkankut on the Crimean Peninsula's northwest coast. The second on September 14th struck a battery 36 miles south in the Yevpatoria. Both strikes reportedly involved the latest version of the Ukrainian navy's Neptune ground-launched anti-ship cruise missile, the original model with which the Ukrainians sank the Black Sea Fleet cruiser Moskva in April 2022 travelled 190 miles with a 330-pound warhead. The new version travels 225 miles with a 770-pound warhead. Ukraine's Luch Design Bureau from the outset designed the Neptune with a GPS-aided radar seeker according to Forbes. Basically the missile navigates to GPS co-ordinates. Once it gets there, the radar looks for something shaped like a worthwhile target. This combination of GPS and radar makes the Neptune equally adept at striking targets at sea and on land although Luch officials have said they tweaked the guidance in the missile's newer model. That could mean the addition of an infrared seeker. In any event, the Neptune works.
