She deployed throughout the Pacific and the western U.S. and Alaska in support of the nation's strategic nuclear triad.

By 1968, Intercontinental ballistic missiles had been deployed and become operational as part of the United States' strategic triad, and the need for B-52s had been reduced.

But the United States must maintain modern nuclear forces including the strategic triad and thus insure the credibility of our deterrent.

The problem Mr. Bush seems to have solved is how to constitute and deploy the land-based leg of the nation's strategic triad of nuclear missiles (the other two legs are sea-based and airborne).

The result would reduce the superpowers' strategic nuclear triads to dyads of sea-based and airborne nuclear weapons.

"We support a strong nuclear deterrent and the strategic triad: strong modern reliable strategic weapons on land, in the air and under the sea," the Senator said.

Politically, the Soviet ballistic missile submarines passed a reasonability check as a part of strategic triad.
