The Caterpillar D399 is a legendary heavy duty V16 diesel engine launched during the 1960s, widely regarded as the “cast iron elephant” of the 1960s-1980s. Featuring a bore of 159 mm and a stroke of 203 mm, the D399 engines are used for continuous duty marine propulsion, power generation and mining. The D399 engine was developed as part of Caterpillar expansion into larger industrial and marine engines, with it gaining popularity in vessels such as tugboats, fishing trawlers and ferries. While modern engines like Caterpillar C18 provide similar power at a fraction of the weight, the D399 is still revered for its durability and long running industrial applications. 

Production of D399 gradually stopped in the 1980s as newer engine models replaced many of its roles. Despite this, several D399 engines remain in service today thanks to their extremely heavy-duty construction and the strong global support network for parts and rebuilds.
