Executive Summary

While the Israeli Naval Yards has been building many larger vessels in recent years, corvette designs have not been approved. Chief of Naval Operations, Fleet Admiral Joseph Jacobson has addressed this issue in his 05-06 State of the Navy Report. He called on the design bureaus in Israel to come up with new designs for corvettes. INY, Israeli Military Industries, and Kineret Defense each came up with competing designs. INY won the contract, but adapted the design to incorporate some of the better systems conceived by the competing designs. The final design of the vessel was 3,175 tons. This made it too large to classify as a corvette. As a result, the vessel was rebranded a patrol frigate.

The Peres was built to fill a void of vessels that can patrol and protect Israel's coast. The vessels are capable of going out on the open ocean and dealing with foreign threats, but that was not the focus of the design board in creating the class. The vessel is the first to mount Israeli Aerospace Industries' Second Generation upgrade of IDIs Mk-1 Mod-0 Integrated Point Defense System.

The export version of this vessel is unable to carry the larger near-hypersonic SSMs, but it can mount the upgraded version of the venerable Gabriel SSM. Domestic versions mount S-14 launchers in place of the standard S-12 launchers. The S-14 allows this vessel to carry four of the USM-8 Jericho Hypsersonic anti-ship missiles. The 24 cell VLS system can carry any arrangement of SAMs or ASW Missiles. In order to save costs, torpedo tubes were not included.

A few minor drawbacks of the vessel are the lack of tubes. The patrol frigate also cannot land a helicopter, but the use of land based maritime patrol aircraft and helicopters makes up for this problem. A third and final flaw is the fact that the point defense fails to cover 45 degrees to either side of the bow. The ship will just have to maneuver appropriately to use its dual point defense systems.

Armament

MISSILES:
4 x IAI S-14 SSM Box Launchers. This is an improvement over the original design which called for S-12 launchers. The larger S-14 launchers can carry the new Jericho Hypersonic Anti-ship Missile. (removable) It should be noted that the provided image shows the S-12 configuration, which will be included on export models.

1 x 24 cell IAI V-2 VLS System in 6 x 4 arrangement. V-2 is a mid sized VLS cell that is used by the Israeli Navy. The individual cell dimensions are .7 m x .7 x 7.5 m. The SPYDER missiles can even be hex-packed in this cell which can also carry anti-ship or land attack cruise missiles along with larger SAMs or even ASW missiles.

GUNS:
1 x 4 inch/55 calibers IMI G-41 with ERGM shells

POINT DEFENSE
1 x IAI/IDI Second Generation Mk-2 Integrated Point Defense System (comprises of)
IAI NSA 3P Box launcher with 21 SAA-4 Point Defense Missiles
IDI NAA 30 mm autocannon with 4,500 rounds


DAMAGE CONTROL:

The vessel contains two DC compartments. The lower deck's DC compartments houses storage for the fluids used in the Israeli Military Industries Shipboard Fire-Fighting System. AMR 2, which is two compartments aft of the tanks containing the fire fighting fluids, contains the pumping mechanisms for this system. On the 2nd deck, DC Central is housed. This is the center where DC operations will be managed. Supplies are housed in the center. Auxiliary DC stations are in CIC, on the bridge, and in the engine room (AMR-3)


Price = 392,157,000 NIS, $600,000,000
