If you’ve ever looked closely at a U.S. Navy warship, you’ve probably seen it — the small white turret with a spinning radar dome perched near the deck, staring out over the sea like a watchful sentry. That’s the Phalanx Close-In Weapon System (CIWS) , the Navy’s last line of defense and one of the most recognizable features on its ships. From aircraft carriers to destroyers and amphibious assault vessels, nearly every major American warship carries at least one. Its rapid-fire cannon and self-contained radar make it the US Navy’s guardian angel — always scanning, always ready, and always the final word when danger closes in.The Phalanx is the last defensive shield for many naval ships. It is designed to protect against missiles, aircraft, drones, and small fast-moving surface threats. Its mission is simple but crucial — stop any incoming danger that slips through outer layers of defense before it can strike the ship.In this video, Defense Updates analyzes what makes Phalanx CIWS so important for US military ?#defenseupdates #Phalanx CIWS #usnavy Chapters:0:00 TITLE00:11 INTRODUCTION01:20 SPONSORSHIP – NordVPN01:54 OVERVIEW04:52 UPGRADES06:21 ANALYSIS
