Three Forty Three is a Ranger 4200 class fireboat that serves the New York City Fire Department as Marine Company 1. It is the largest single-purpose fireboat built to date with the highest pumping capacity of any fireboat ever built.

The Three Forty Three was built by Eastern Shipbuilding of Panama City, Florida, and is the largest single-purpose fireboat built to date with the highest pumping capacity of any fireboat ever built. 

The 140-foot, 500-ton, $27 million fast response boat is the country’s largest fireboat, with a maximum speed of 18 knots. The Three Forty Three incorporates the latest technology available for marine vessels, including the capability of pumping 50,000 gallons of water per minute, nearly 30,000 gallons more than its predecessor. It has an operating crew of seven.

The boat’s name comes from the number of FDNY members killed in the line of duty on September 11th, 2001. It is one of four New York fireboats currently in active service.
