SINGAPORE - Singapore Technologies Engineering Ltd STEG.SI said on Wednesday it has won a contract worth up to $1.94 billion to build as many as three icebreaker ships for the U.S. Navy.

The U.S. Department of the Navy awarded VT Halter Marine, ST Engineering's shipbuilding business in Mississippi, a $746 million contract for the detail design and construction of the U.S. Coast Guard (USCG) polar security cutter, the Singapore-based company said in a statement.

The first ship is due for delivery in 2024, said ST Engineering. It said the contract is worth $1.94 billion, including options for two more vessels with estimated delivery dates of 2025 and 2027.

The United States has two operational icebreakers - the Polar Star, which is more than 42 years old, and the Healy. urn:newsml:reuters.com:*:nL1N1YB2IP
