The Israeli Navy has followed the world lead in acquiring a more modern, "stealth-centric" corvette warship through the INS Eilat (501) and her kind. The class numbers three warships with lead ship Eilat launched in February of 1993 and commissioned on May 21st, 1994. As of 2016, she maintains an active status in the Israeli Navy. She was built by Ingalls Shipbuilding (Northrop Grumman) in the United States.

INS Eilat is categorized as a corvette with her primary role being that of missile boat. As such her armament suit is dominated by missile weaponry and she lives-and-dies through her available speed and agility. Power is provided for through a COmbined Diesel Or Gas (CODOG) engine arrangement in which one propulsion scheme can be selected over the other to minimize fuel consumption and maximize speed output (useful in "dashing" actions). The diesel units are 2 x MTU V12 1163 TB82 systems coupled with a General Electric LM2500 gas turbine. Maximum possible speed is in the vicinity of 33 knots under gas turbine power with ranges out to 3,500 nautical miles.

On board, Eilat is crewed by 74 personnel including a 10-man air wing. Her rear section houses a full-service helicopter hangar and helipad for launching/recovering and servicing a single Eurocopter Panther helicopters. The vessel carries the Argon ST AN/SLQ-25 "Nixie" decoy system as well as an Elbit chaff rocket launcher. Rafael provides the RF corner reflector / wireless jammer and Elisra the NS-9003A/9005 Radar Warning Receiver (RWR). Elta supplies the air-search and fire-control radar fits while EDO provides its Type 795 sonar system. Rafael is responsible for the towed sonar array.

Armament is led by 8 x RGM-84 Harpoon anti-ship missiles. This is supported by 64 Barak 1 surface-to-air missiles protecting the main superstructure. For close-in defense, the vessel is outfitted with the 20mm Phalanx Close-In Weapon System (CIWS) seated over the forecastle. A pair of Mark 32 triple torpedo tubes are also carried for dealing with undersea and on-sea threats. All told, INS Eilat can handle nearly any threat form approaching the vessel or the fleet it protects.

As built, Eilat sports an overall length of 281 feet, a beam of 39 feet and a draught of 10.4 feet. She displaces 1,075 tonnes under standard loads and 1,227 tonnes under full loads. The masts are only partially enclosed, adding some stealth qualities. The bridge is well-contoured to the forward superstructure and the smoke funnels - near midships - are of a low-profile and enclosed design. Additionally, hand rail sections are kept to a minimum, allowing the warship to exhibit a slab-sided appearance, further aiding her radar reduction.
