The Espora-class corvette is armed with one 76mm (3 inch) naval cannon, a deck-mounted MM38 Exocet (French-made anti-ship missile) launcher (4 missile capacity), two 40mm DARDO CWIS anti-aircraft guns and two triple torpedo launchers loaded with French WASS A-244S light torpedoes.
Admiral Chandler recounts the story of Captain Nathan James, the sailor the ship is named after. He said he was the skipper of a PT boat in the Pacific theater during World War II. A Patrol Torpedo (PT) boat was a small, fast inexpensive vessel designed to attack surface ships with torpedoes then quickly move out of range of said ship's guns. A typical WW-II PT boat was 80 feet in length, 20 feet in draft, weighed 56 tons displacement, was powered by three 1,500 horsepower Packard V-12 engines with a top speed of 41 knots (47 MPH). Each PT boat had a crew of 3 officers, with a Lieutenant as the CO and a Lieutenant Junior Grade as an XO (sometimes an Ensign), and 14 enlisted men. They were armed with four MK-8 torpedoes, each weighed 2,600 pounds and had a warhead with a yield of 466 pounds of TNT; one forward mounted 37x144mmR M4 autocannon, one aft 20×128mm L85 autocannon and two twin .50 caliber Browning M2 anti-aircraft machine guns.
