6.3 Flectromagnetic Effects - (ESL) AFS.P wishes to re-examine this project. The proposal came in. before Ivy data were reduced, and Scoville stated that if these data are mulfecpent they will not wart to do this again, || iGz Proof Testing of Atomic ‘arfare Countermeasures - (NRDL, CRL) techniqu spray vith all alte discussed above, this is the BuShips proposal to test the Maving to do with decontaminating a ship, involving vent closures, ah etc., and would entail two drone Liberty ships, one equipped e //~gountemmeasures, the other not so equipped. It is apparently quite important|ito the Navy, since further design and production of these devices will hi on the results. They discussed having the ships manned and further away’but decided the data to be gained by putting them closer and using drones were worth the increased cost and effort. They want them inside a possible base surge, if there is one, but sufficiently outside the blast range; distances 26 to 10 miles are being talked of. The ships mst be moving since the spray svFien operated only if there is a relative novement to the vessel. } Ogle asked sadgit was necessary to test these countermeasures close to a banb, why not spray, ‘ohm with debris frem a pile? Scoville replied that the activity must be in sol form, the way it is. received fram a shot. The greatest probl pe.is an operational one with regard to the Task Force has discussed this— there has been consideration of cqntyplling the ships by a plane flying, or from another ship—and have concluda/ it will require a clear channel systen, a group of radio frequencies (the mumbe yet determined), in order to for a helicopter to take the ensure safety.
