Question

How long did the Navy continue using propeller-driven attack aircraft after WWII?

Answer 1

More than 20 years

Step-by-step explanation:

Even though the first catapults used by the Navy were put to work with compressed air, in the course of World War II the flight deck catapults on the front-line carriers of the Navy were used occasionally. Nowadays, aircraft carriers are provided with steam catapults.

Answer 2

I believe the answer is around 25 years.
The propeller-driven attack was used in world war II that ended in 1945 and stopped being used in 1970
Back then, this aircraft was favoured due to the advantage in travel speed and the height that the pilot could achieve.
