	NIPPI 12-Shi Primary Trainer Seaplane In 1937, as the 90-Shiki Primary Trainer Seaplane outdated, the Japan Navy ordered NIPPI and two other companies to produce a prototype of the 12-Shi Primary Trainer Seaplane. NIPPI worked on its first original design aircraft. The aircraft was completed and delivered to the Navy's aero technical institute for evaluation test. The test results were favorable.

Kawasaki-Lockheed P-3C Although its predecessor passenger aircraft Electra was not a blockbuster, the Kawasaki¥Lockheed P-3C scored a great success as an antisubmarine patrol plane with its wide cabin capacity and long-haul cruising range. It also has derivatives as an electronic warfare trainer, a transport, a maritime patrol plane and more. They have been used in many countries across the world. NIPPI has been working on modification of these aircraft models among the U.S. Navy fleet since 1967 and the same for the Japan Self Defense Force since 1988. NIPPI Aerospace Division was in charge of its engine nacelle production.

	Hughes TH-55J The Hughes TH-55J for the Japan Ground Self-Defense Force (Hughes 300 as commercial Model) came as an eye-opener with its novel configuration and structure in the heyday of Bell 47's popularity. At the initial phase of its introduction, NIPPI reviewed the feasibility of the model's licensed production in Japan and also worked together with Aerospace Technology Institute in conducting the performance evaluation tests etc. At Atsugi Plant (now Aircraft Maintenance Division) later on, NIPPI conducted the modification work on the Japan Ground Self-Defense Force's 161 trainers of this model in the period between 1948 and 1994.

Northrop Grumman E-2C Hawkeye The Northrop Grumman E-2C Hawkeye was developed as an Airborne Early Warning (AWE) plane, a brainchild from the concept that an airborne radar would enable patrol of longer range. Although it had a spate of glitches with the electronic systems during the Vietnam War, it has been improved ever since. Now the models are operated by the Japan Air Self-Defense Force and also in Israel, Egypt, France, Singapore and many other countries. NIPPI has been engaged in its modification effort since 1968.

	Navy 93-Shiki Intermediate Trainer The Navy 93-Shiki Intermediate Trainer was developed as an intermediate trainer by the Japan Navy itself. It enjoyed a good reputation to have the higher performances than in-service airplanes at that time. Over the 11-year period from its commencement of production in 1934 through the termination at the end of the WWII, a combined total of 5,591 airplanes of this model were built as landplane and seaplane, out of which NIPPI built 2,733 airplanes. Dubbed "red dragonfly" after its orange painting on its body, along with the Japan Army's 95-Shiki Trainer, the model was popular among Japanese.

Douglas AD-6 Sky Raider The Douglas AD-6 Sky Raider, the last carrier-borne prop air raider, made its first flight in 1945 and successful debut in the battlefield of the Korean War. With its 3,180th ship set, its production was terminated in 1957. Proving powerful, however, in the counter-guerrilla combat in the Vietnam War, it continued serving at the forefront until around 1979. NIPPI modified its 138 ship sets between 1960 and 1969.

	Super-Marine Southampton In 1936, NIPPI modified a military reconnaissance seaplane, the Super-Marine Southampton, into a passenger seaplane upon request of Japan's first civil air transport service company, Japan Air Transport Research. Named "KIRIN-GO" after its sponsor brewery company's name, this plane was in service in the Kansai district (the southwest part of Japan). The Southampton was purchased by the Japan Navy from the U.K. for study in 1927, and later on disposed after completion of the performance evaluation tests.

Grumman GM TMB-3 Avenger Grumman GM TMB-3 Avenger served as a torpedo bomber in the WWII. The Japan Maritime Self-Defense Force, at the time of its inauguration in 1954, was furnished with 10 pairs (20 ships) of antisubmarine patrol planes comprising TBM-3W (search plane) and -3S (attack plane) by the U.S. Forces. NIPPI, in 1954, entered into a contract with the Japan Self-Defense Force on the modification of this model, and performed the work at its Sugita Plant (now Aerospace Division).

	Saab 340 Saab 340 came as Saab, builder of Draken, Viggen and other unique fighters, branched out into the commuter aircraft market around 1980. Many of this model have entered service in U.S. and Europe's local lines, as well as 14 units in Japan's Kyushu district (the South), Hokkaido (the North), etc. NIPPI has been engaged in periodic maintenance and modification of radar systems etc. on 2 of this model for the Japan Maritime Safety Agency. The two were introduced as search-and-rescue aircraft by the Agency in 1997.

Boeing 757-200 As the Boeing 767 became larger, an aircraft with smaller body, the Boeing 757 was developed. Unlike other Boeing models, this model has had only one type (the 757-200), until recently. Now it has the derivative, 757-300. The 757-200 first entered service in January 1983. NIPPI has long been building elevators for this aircraft under the direct contract with Boeing. NIPPI's elevators widely employ composite materials to reduce weight. NIPPI's Aerospace Division has delivered a cumulative total of 650 ship sets of the elevators since its first delivery in April 1990.

	NAMC YS-11 The NAMC YS-11, a passenger of Japanese make first after the WWII, made its first flight in 1962. It was built until 1972 with its 182nd being the last unit. As of May 2002, 28 units of this model are in service in foreign countries and 50 in Japan. NIPPI, now in charge of the modification of this aircraft for Japanese government agencies, has re-engined 6 units of the Japan Air Self-Defense Force's fleet. Also, NIPPI had made a mock-up of this model as well as built ailerons, flaps, stairways, etc. for the aircraft.

TRDI X1G1 Saab Safir NIPPI modified the Saab 91 Safir into a high-lift experimental plane, i.e. TRDI X1G1 Saab Safir in the period between 1954 and 1957. The effort included major modifications such as upgrading engine power, redesigning wings and tail planes, retrofitting diminutive gas turbine for air supply, etc. The fruits of the experiments on double-slotted flap, horizontal tail plane leading slat, full-span flap and spoiler were incorporated into UF-XS, PS-1 Seaplane, C-1 Transport, etc.

	North American F-86F Saber Making its debut as the world-fastest fighter, the North American F-86F Saber won fame by air combat with the MIG-15 during the Korean War. 3,400 units were built since its first flight in 1947 for the service in 26 countries. NIPPI (then Tachikawa Plant) was engaged in the model's modification effort starting in 1956 and continuing through 1959.
