another Mediterranean deployment in April 1970 and embarked 6th Fleet's Service Force Commander at Naval Station Rota, Spain. Again, as in 1967, Truckee was on the scene when new violence threatened in the Mideast. From 9 September 1970 until 8 October, the tanker supplied the naval forces standing off the coast of Israel during the Jordanian Crisis. Pumping day and night during 27 of her 30 days at sea, she earned the Meritorious Unit Commendation for her performance. On 18 November, Truckee returned to Norfolk and began the conversion of her plant to burn Navy Distillate Fuel. The oiler plied the Atlantic from Nova Scotia to the Virgin Islands in 1971, supporting NATO and Atlantic Fleet operations. She participated in Exercise "Rough Ride" in June. After that 10-day NATO exercise involving ships from five countries, she supported a NATO sea power demonstration off Norfolk in September. February 1972 found Truckee again underway, via the Caribbean, for the Mediterranean. At the end of this deployment with the 6th Fleet, she returned to the east coast in November and, at year's end, had pumped a total of 189 million litres (50 mio. US gal) of fuel. On deployment with the 6th Fleet again in 1973, Truckee provided support during yet another Middle East crisis, the Yom Kippur War. After an emergency sortie from Palma de Mallorca on 7 October occasioned by the heaviest Arab-Israeli fighting since 1967, Truckee remained in the eastern Mediterranean until ordered to standdown from alert posture on 18 November 1973. During this cruise, the tanker pumped 95 million litres (25 mio. US gal) of fuel to NATO and United States ships and steamed 40,000 km (25,000 mi). In 1974, Truckee remained on the east coast operating out of Norfolk. She also underwent an extended overhaul which took seven and one-half months and was not completed until January 1975. In the summer of 1975, she participated in Exercises "National Week" and "Dawn Patrol" in the eastern Mediterranean. Later in August, she shifted operations to the western Mediterranean before departing Rota, Spain, in October at the end of her 10th Mediterranean deployment. On 3 November, she returned to Norfolk for overhaul. In February 1976, she returned to duty with the 2nd Fleet operating out of Norfolk with occasional visits to other east coast ports. Second Fleet operations took Truckee to Guantanamo in May and to Puerto Rico in July, and
