In February 1946,
Leonard Peto, owner of the former-
Montreal Maroons NHL franchise, announced plans to revive the franchise in Philadelphia for the 1946-1947 NHL season as the league's seventh team. Peto and his partners identified the Phillies'
former ballpark site at Broad and Huntingdon for their planned 20,000 uptown arena.
Philadelphia Arena owner Pete Tyrell protested that the
American Hockey League held territorial rights to Philadelphia, and planned himself to build a larger arena for ice hockey in Philadelphia. Peto's bid would prove unsuccessful, and Tyrell would not build a larger arena, but the AHL responded to the threat of an NHL franchise by admitting the
Philadelphia Ramblers for the 1946-1947 season. The Rockets played for three seasons in the AHL from 1946 to 1949. Philadelphia had previously had a team in the league during the
1941–42 AHL season known as the
Philadelphia Ramblers. When the Ramblers had folded in 1942, they were replaced at the Philadelphia Arena by the
Philadelphia Falcons who played in the
Eastern Hockey League. In 1946, the Falcons were replaced by the second Rockets team in the AHL. Four members of the Falcons (
Vic Lofvendahl,
Harvey Jacklin,
Clayton Lavell,
George DeFilice), made the jump to the higher league. The Rockets had a
farm team affiliation with
Galt Rockets in the
junior ice hockey division of the
Ontario Hockey Association from 1947 to 1949. ==Season-by-season results==
