El-Op's MSIS electro-optic surveillance and fire control system is fitted on the Eilat, which contains an 
8 12 micron thermal imager, TV camera and laser rangefinder.

Harpoons
The ship has two four-cell Boeing Harpoon missile launchers. The Harpoon surface-to-surface missile has a range of up to 130km. The speed is high subsonic and the warhead weighs 227kg.
The Harpoon is a subsonic, sea skimming guided missile utilizing active radar guidance. Warhead design and low-level sea-skimming cruise trajectory assure high survivability and effectiveness. The missile is capable of striking surface targets at a maximum range of 130 kilometers (60 nautical mites). Harpoons are deployed on Israeli Navy surface ships and submarines. Ships are usually equipped with two batteries of four container/launchers each.
The 4.57 meters long missile weighs 520kg, (628kg before launch) and is powered by a Teledyne Turbojet generating 660 pounds of thrust. Upon launch, the missile is boosted to cruise speed by a solid propellant booster. In mid course the missile flight is controlled by an altimeter and inertial guidance system. At a preplanned point, the missile's radar is activated and searches for the target. When the target is detected, the missile uses its own radar for guidance terminal homing. With a high impact velocity the missile's blast fragmentation charge uses delayed action to penetrate the target's hull and inflict maximum damage.

Gabriel
The ship's short to medium-range anti-ship missile is the IAI Gabriel II. There are eight launchers for the Gabriel II missile which uses dual mode semi-active and active radar homing with a 100 kg warhead. The range is from 6 to 36km and missile velocity is 0.6 Mach.

Dolphin
A maritime reconnaissance helicopter that served in the IAF for a decade, and was recently replaced by the more advanced 'Atalef' SA-565. The 'Dolphin' helicopters were deployed from the Israeli Navy's 'Sa'ar' ships, and carried out routine security missions as well. The Dolphins were purchased from the Israeli Navy's budget, but responsibility for them was shared.The helicopters were the IAF's responsibility as long as they were airborne, and the Navy's when aboard a ship.

Atalef (Panther)
A sea helicopter that entered service in 1996. The Atalef operates off of Israeli Navy Sa'ar-5 missile boats and carries out a range of operations, including rescue, reconnaissance and targeting. It replaced the IAF's previous sea helicopter, the Dolphin. The crew complement is made up of a pilot, a copilot and a sea scout from the Navy. On some missions, these are joined by a flight mechanic.

The Sa'ar is equipped with Type 796 hull-mounted search-and-attack sonar, which operates at medium frequency and is supplied by EDO of New York. The ship's towed sonar array is supplied by Rafael.
