1. Lockheed TV-1 advanced jet trainer.
2. They had NO arresting gear and, like most early jet aircraft had NO ejection seat.
3. Bonus answers-VMF-311. USS Franklin D. Roosevelt, CVB-42 for P-80/TV-1 initial sea trials.
In 1948 the U.S. Navy acquired three Lockheed P-80A Shooting Star jet fighters from the USAF for evaluation. One, modified with an arresting hook, was used for deck landing trials aboard the USS Franklin D. Roosevelt, CVB-42 Midway Class straight deck aircraft carrier. Later the same year the Navy decided to acquire 50 of the P-80s for use as advanced jet trainers, re-designating them as TV-1s. They had no arresting gear nor were they ejection seat-equipped. Despite their training role, 16 of the TV-1s were used to equip a front-line Marine fighter squadron, VMF-311 late in 1948.
There may have been some reader confusion in this quiz because the aircraft in U.S. Navy usage had multiple designators, Lockheed TO, TV and T2V Seastar with sub-variants such as TV-2D and TV-2KD. Also, the Navy changed Lockheed's symbol designator from O to V. Additional confusion came in 1962 when new designations of the Lockheed family were T-33B (TV-2), DT-33B (TV-2D) and DT-33C (TV-2KD). Also, readers may have been thinking a jet fighter rather than trainer aircraft for aircraft carrier use.
