INS Atzmaut is a Sa'ar 6-class corvette of the Israeli Navy's Shayetet 3 Flotilla.

The Sa'ar 6-class corvettes' design will be loosely based on the German Braunschweig-class corvette, but with engineering changes to accommodate Israeli-built sensors and missiles such as the Barak 8[4] and the naval Iron Dome system.

Elbit Systems has been awarded the contract to design and build the electronic warfare (EW) suites for the ships.

[citation needed] The Sa'ar 6-class vessels have a displacement of almost 1,900 tons at full load and is 90 m (295 ft 3 in) long.

They are armed with an Oto Melara 76 mm main gun, two Typhoon Weapon Stations, 32 vertical launch cells for Barak-8 surface-to-air missiles, 40 cells for the C-Dome point defense system, 16 anti-ship missiles Gabriel V,[5][6] the EL/M-2248 MF-STAR AESA radar, and two 324 mm (12.8 in) torpedo launchers.
