At the end of 1970, the 10th Squadron replaced the

and the 24th Aerospace Defense Squadron. WS 437 was put into standby status with the squadron maintaining system components. The squadron then changed its mission to support of the

(DMSP). The DMSP mission was performed by Strategic Air Command until it was transferred to ADC in 1970.Hall, p. 33 The DMSP generates terrestrial and space weather data for United States operational forces worldwide. Data from this program is also furnished to the civilian community through the Department of Commerce. DMSP satellites circle the Earth at an altitude of about 500 miles in a near-polar, sun-synchronous orbit. The Block 5 DMSP satellites launched during the time the squadron was active used Thor launchers (similar to those used by WS 437) to boost them into orbit. In 1979, the squadron was inactivated when responsibility for management of the DMSP program was transferred to Space Division of AFSC. Unfortunately, the squadron remained responsible for operational DMSP launches, "the FSCprogram office authorized launch of the last Block 5C satellite on 19 February 1976 with incorrect weight-to-propellant-loading calculations. Launched from Vandenberg Air Force Base, the Thor/Burner II booster rose majestically through the atmosphere, reached the edge of space, exhausted its propellant, and the DMSP satellite whistled back to Earth—a total loss."
