Aircraft, Propeller, Nakajima B6N Jill

History: The Nakajima B6N Tenzan (Japanese: 中島 B6N 天山—"Heavenly Mountain", Allied reporting name: "Jill") was the Imperial Japanese Navy's standard carrier-borne torpedo bomber during the final years of World War II and the successor to the B5N "Kate". Due to its protracted development, a shortage of experienced pilots and the United States Navy's achievement of air superiority by the time of its introduction, the B6N was never able to fully demonstrate its combat potential.

Railroad/Company: The Nakajima Aircraft Company (中島飛行機株式会社 Nakajima Hikōki Kabushiki Kaisha) was a prominent Japanese aircraft manufacturer and aviation engine manufacturer throughout World War II. It continues to the present day as the car and aircraft manufacturer Subaru.

Japan's first aircraft manufacturer, it was founded in 1918 by a naval engineer, Chikuhei Nakajima, and a textile manufacturer, Seibei Kawanishi as Nihon Hikoki (Nippon Aircraft). In 1919, the two founders split and Nakajima bought out Nihon Aircraft's factory with tacit help from the Imperial Japanese Army. The company was renamed Nakajima Aircraft Company in 1919.

The company was reborn as Fuji Heavy Industries, maker of Fuji Rabbit scooters and Subaru automobiles, and as Fuji Precision Industries (later renamed Prince Motor Company which merged with Nissan in August 1966), manufacturer of Prince Skyline and Prince Gloria automobiles. Fuji began aircraft production in the mid-1950s and has been producing military training aircraft and helicopters for the Japan Self-Defense Forces. In 2017 it rebranded as Subaru Corporation.
