Thud Ridge was the nickname given by United States Air Force F-105 "Thud" pilots during the Vietnam War to the Tam Dao range a 24km, 5000ft high ridge that ran parallel to the Red River approximately 32km northwest of Hanoi, which was both a waypoint during air attacks and a terrain masking feature for ingressing fighters in the vicinity of Hanoi, North Vietnam.[1][2]

The North Vietnamese eventually installed anti-aircraft artillery on the ridge using heavylift helicopters.[3]

Phúc Yên Air Base is located at the base of the ridge, while Kép Air Base is located east of the ridge.

The ridge features heavily in Thud Ridge (book).
