PCE-842-class patrol craft

The Patrol Craft Escort was a World War II naval ship that was intended as a coastal and convoy escort. It was derived from the 180 foot as a substitute for the 173 foot  that was used for Anti-submarine warfare (ASW) in coastal areas. At 185 feet long and 640 tons, the PCE is more than twice the displacement of the PC. It has a crew complement of 99 officers and men.

Development and design
The Admirable class had been developed as a smaller minesweeper than the and s, which would be cheaper and easier to build, while still having good seakeeping capabilities in high seas. An escort derivative of the new design was proposed for supply under the Lend-Lease scheme to Britain's Royal Navy (which had already rejected the Admirable -class as minesweepers), and when the US Navy realized that a shortage of engines might prevent it from receiving additional beyond those already on order, it was decided to build the escort variant, designated as PCEs (Patrol Craft Escort) for both the US Navy and Royal Navy.

Engines
The PCE has two 1,000 HP diesel engines driving two shafts and two propellers giving it a 16 knots maximum sustained speed and a range of 8,000 miles at cruising speed of 13 knots.

Armaments
The usual PCE armaments are a dual-purpose 3"/50 cannon, three 40mm Anti-Aircraft guns, four 20mm guns, and two depth charge tracks. Some were later fitted with torpedoes, rockets, hedge hogs, and Heavy Machine Guns.

Detection equipment
The PCE was fitted with radar, and sonar and other detection equipment for Anti-Submarine Warfare (ASW).

Conversions
Some PCEs later were converted to PCE(R), Rescue Escorts, and to Amphibious Control Vessels, PCE(C)that were used in many U.S. amphibious landing operations in World War II specially Leyte Gulf and Normandy.

Production
Sixty Eight (68) Patrol Craft Escorts were built for the US Navy, and seventeen (17) were delivered under the Lend-Lease Program to Allies during World War II. The PCEs proved to be an inexpensive substitute for larger and more valuable DD's and DE's in convoy escort work.

Philippine Navy
In 2014, the Philippine Navy still operates the with six PCE's as gun corvettes, with all the ships' ASW equipment already removed. The PCE is the most numerous major ship class of the Philippine Navy that, at one time, numbered more than ten vessels.
