TG Grade syntactic foams are lightweight and economical for building manned and remote operating vehicles. The foams have also been used in mine neutralization systems because of their zero magnetic and sea water comparable acoustic signatures and to fabricate eyebrows for 688-class US nuclear submarines because of their buoyancy, acoustic profile and ability to significantly improve sonar functions.
