10. The U.S. Navy in Vietnam ROLLING THUNDER TF 77 (CVs) North Vietnamese bombing campaign. 1. MARKET TIME/GAME WARDEN TF 115 and TF 116 (PBRs, PCFs, ATCs) Coastal and Mekong Delta Interdiction 2.

11. 1. “Rolling Thunder”, 1965-1968 • Theory: punish NV until it stops supporting Viet Cong in South. • Reality: Very Costly • 304,000 fighter bombers and 2,380 B-52 sorties • 421 aircraft lost, 1965-1968 • 643K tons of bombs dropped (537K dropped in entire Pacific War.)

12. Rolling Thunder Evaluation “Rolling Thunder must go down in the history of aerial warfare as the most ambitious, wasteful, and ineffective campaign ever mounted. While damage was . . . done to many targets in the North, no lasting objective was achieved. Hanoi emerged as the winner of Rolling Thunder.” (CIA analyst quoted by COL Harry Summers, USA, Historical Atlas of the Vietnam War, p. 96)

13. 2. Operation Market Time, 1965-1972 • The Goal: • Deny use of Mekong River and tributaries • Interdiction of supplies. • Highly Dangerous • Less effective and more costly than coastal interdiction • Specially Designed and Improvised Force • 50 FT, aluminum hull fast patrol craft (PCFs), .50 cal and 81-mm • 31 ft, fiberglass, river patrol boat. • Coast Guard Cutters

14. Market Time Evaluation Outstanding Evaluation: “From January to July 1967, Market Time forces . . . inspected or boarded more than 700,000 vessels in South Vietnamese waters. Except for five enemy ships [sighted during Tet] . . . no other enemy trawlers were spotted from July 1967 to August 1969.” (COL Harry Summers, USA, Historical Atlas of the Vietnam War, p. 150) Cautious Evaluation: “There are no statistics to show what MARKET TIME did not interdict. At the very least, MARKET TIME forced the enemy to be even more inventive and creative in bringing into the South the tools of war.” (Symonds, Historical Atlas of the U.S. Navy, p. 210)

15. The Tet Offensive: The Turning Point • WHEN: Jan, 1968 • WHO/WHAT: Combine attack by North Vietnamese and Vietcong. • 80k N.
