GUAM, Aug. 7, 1945 (UP) - American Superforts and fighters raked Japan with bombs and strafing fire in what Tokyo radio indicated may have included another atomic bomb attack.
Disclosure of the new strikes came only a few hours after front dispatches reported that more than 400 fighters and bombers of Gen. George C. Kenny's Okinawa based Far Eastern air force demolished a Japanese "mystery town" Sunday in what may have been an attack on newly developed Japanese rocket launching installations.
Tokyo radio reported that 100 American planes, including heavy bombers and fighters, attacked Toyokawa naval arsenal this morning, and language of the report, which was similar to an imperial headquarters communique announcing Monday's atomic bomb attack on Hiroshima, led to a belief that Toyokawa may also have been a target for the new weapon.
Shortly before the Tokyo report, Gen. Carl A. Spaatz, commander of the United States strategic air force in the Pacific, announced that 125 Superforts hit Toyokawa with 880 tons of high explosive bombs. Toyokawa 35 miles southeast of Nagoya on the south-central Honshu coast.
Spaatz' announcement made no hint that the raid included an atomic bomb attack, but preliminary reports indicated that excellent results were achieved in pinpoint bombing.
The attack was made at noon, the first Superfort daylight strike in recent weeks, and the silvery giants were escorted by Iwo-based fighters.
Toyokawa is the main surviving source of Japan's naval ammunition. The arsenal also turned out machineguns, aircraft, cannon, antiaircraft guns and rifles.
Tokyo radio admitted that "some damage" was caused during the 90-minute raid. "However," the broadcast continued, ''a report on the exact extent of damage done is as yet unavailable."
Tokyo radio also said 40 Iwo-based Mustang fighter bombers bombed and strafed military installations and urban areas in the Tokyo-Yokohama area for an hour for the fourth time in five days.
Several British planes participated in the Tokyo raid, according to the enemy broadcast. If confirmed, it would be the first time British land-based places have been in action against the enemy homeland.
Belated dispatches from Okinawa, released by Gen. MacArthur's communique announcing Sunday's attack on Taramuzu in southern Kyushu, said 400 bombers and fighters of the Far Eastern air force utterly demolished what appeared to be robot plane launching installations and other military targets there. Airmen said the city of Taramuzu itself was left a sea of flames. Liberators, Mitchells, Invaders, Mustangs and Thunderbolts participated in the strike, the heaviest yet made against Japan by the Far Eastern air force.
Returning pilots told of seeing a huge catapult-like machine extending over the water. It appeared to be similar to the rocket-launching devices used by the Germans in their bombardment of Britain.
They also reported seeing a number of small planes which looked like the rocket robots the Germans used.
Taramuzu, an aircraft center and city of 17,000 on the east shore of Kagoshima bay, lies only about 350 miles from Okinawa and it would be possible that the Japanese were preparing a rocket campaign against that American base.
United Press War Correspondent Russell Annabel reported from Okinawa that veteran pilots who flew in Europe said the destruction of Taramuzu, on which tons of jellied gasoline bombs were dropped, was the most complete they had ever seen.
He quoted officers as saying all military objectives were "utterly demolished."
