3M Co. has won an $80 million contract to make stronger combat helmets for the U.S. Marine Corps, company officials announced Tuesday.

The contract means the Maplewood-based conglomerate better known for making Scotch tape and Post-it notes will manufacture 77,000 rugged combat helmets with 50 percent more protection than Marine helmets currently in use.

3M begins delivering the helmets this fall, and Marines are scheduled to get them early next year. Other terms of the contract were not disclosed.
