The Grumman Aircraft Engineering Corporation, later Grumman Aerospace Corporation, was a 20th century American producer of military and civilian aircraft. Founded on December 6, 1929, by Leroy Grumman and his business partners, it merged in 1994 with Northrop Corporation to form Northrop Grumman.

During World War II, Grumman became known for its "Cats" (Navy fighter aircraft): the F4F Wildcat and F6F Hellcat, the Grumman F7F Tigercat and Grumman F8F Bearcat, and also for its torpedo bomber, the Grumman TBF Avenger. Grumman ranked 22nd among United States corporations in the value of wartime production contracts. Grumman's first jet aircraft was the F9F Panther; it was followed by the upgraded F9F/F-9 Cougar, and the F-11 Tiger in the 1950s. The company's big postwar successes came in the 1960s with the A-6 Intruder and E-2 Hawkeye and in the 1970s with the Grumman EA-6B Prowler and F-14 Tomcat. The U.S. Navy still employs the Hawkeye as part of Carrier Air Wings on board aircraft carriers, while the U.S. Marine Corps, the last branch of service to fly the Prowler, retired it on March 8, 2019.

Apollo Spacecraft: Apollo Lunar Module Diagram

Grumman was the chief contractor on the Apollo Lunar Module, the first spacecraft to land humans on the Moon. The firm received the contract on November 7, 1962, and built 13 lunar modules. Six of them successfully landed on the Moon, with one serving as a lifeboat on Apollo 13, after an explosion crippled the main Apollo spacecraft. LM-2, a test article which never flew in space, is displayed permanently in the Smithsonian Institution.As the Apollo program neared its end, Grumman was one of the main competitors for the contract to design and build the Space Shuttle, but lost to Rockwell International.

Coaster is 100mm and 3mm thick. Design prints on 2 layers, face down, so as to maximize detail. If you move the prime tower, you can easily fit 5 of these on a 256x256 build plate. 3D Model is of the logo itself. Disc was added in Bambu Studio to create the coaster.
