The Navy Project Manager for coordination and execution of DOD responsibilities for rendering logistics support tq this Survey is Commander, Pacific Missile Test Center, - Mugu, California. a. PHASE I. Initially, support will be proviBRed for a photographic survey of eleven (11) atoils and two (Rk) islands in the Northern Marshall Islands utilizing a DON EC#121 a@ircraft. This platform has been specially configufed to receive DOE-provided high resolution and infra-red Fapable cameras, plus additional peripheral support equipmeht. (1) Phase I will be accomplished under the operational direction of the Project Manager (COMPMEC), in accordance with the technical direction and advice Bf the On~Site DOE representative and the (2) terms of this MOR. COMPMTC will promulgate an appropriate Operations Directive for mission. the accompiishment of the Phase I b. PHASE II.
