- Discussing Grumman's F7F 3P Tigercats, F4F 3 Wildcat, F8F 2 Bearcat and F6F Hellcat.
Grumman's claim to fame in the aerospace field is their iconic Big Cat line of Navy fighters, dating back to the F4F Wildcat in the late 1930s. The carrier-borne fighter designs that began with the Wildcat and ended with the F-14 Tomcat of “Top Gun” fame were chiefly fighters; their names were taken from different feline species or, during the World War II years, a derivative of the “cat” name with an adjective in front of it. Grumman’s first fighters for the U.S. Navy were barrel-chested biplanes, known only as the F2F and F3F; they had no nicknames.
It is striking how few different types of the US Navy operated during World War II, particularly from carriers, and how nearly all of them were either totally brilliant or just awful.
The Grumman Aerospace Corporation now known as Northrop Grumman made history by providing combat-proven carrier fighters to the United States Navy. Each of these incredible fighter aircraft was not only advanced for their day but would have Grumman’s unique style of being named after cats that became near-synonymous with Grumman’s Navy fighters.

I was visiting the Air Museum in Kalamazoo, Michigan on a day all the cats were to go up and fly in formation to be photographed by a B25 with guns and rear glass removed so photos were taken.
Time was early 1980`s and a short grey haired old man with a crew cut got in the F4F and flew it. Word was he actually flew the type in the war. It was a memorable day 40 years ago.
We need a new kitty from Grumman
It's Northrop Grumman now.
The group flight: AWESOME!!
Tigercat: huge engines, skinny fuselage😮
There are a few inaccuracies. The Hellcat was not merely an upgrade to the Wildcat as is often asserted. The Hellcat was a completely new design and any cosmetic similarities are strictly coincidental.
They were also kind of Dickheadish to the fans. the average person has no idea about the terms they were using and the speeds in knots was kind of stupid instead of giving MPH. i guess having money does that to a person.
General McIlhenny, The Hellcat is my favorite A/C, after the F-4D, of course!
37:53 what about Korea? I saw only f86 and mustang and corsair
