A rather advanced ship that was pioneered and constructed by the Trade Union. Her keel was laid down in Year 82, and construction proceeded slowly. She was ready only a month into the Second Infinitas War, and guarded the port of Marsilion from hostile incursion until she was boarded and captured by amphibious and aquatic citizens working for Saber during the Battle of Marsilion, whereupon she continued in Marsilion Navy service.
The Tobin is an all-metal corvette powered by three diesel engines, and was rather expensive to design and build. It is currently considered the most advanced ship upon the island. With a crew compliment of 75 enlisted, midshipmen, officers and staff and an endurance of three weeks, she is able to take the fight to any part of the island's shores. Her armament includes a 75mm electic-powered naval autocannon that fires at 100 RPM at the prow, along with a pair of 20mm anti-air guns at her flanks. A mounted recoilless rifle upon the conning tower and a rear-mounted short range naval SAM system rounds out her armament.
The Tobin can often be seen in the Marsilion harbor, either docked or in shakedown patrols and cruises. Due to the large operating expenses her deployment brings, she is often kept running on a skeleton crew in a secure pen in the harbor, ready to sail within several hours.
