This is an injection-plastic jet aircraft model kit.
From the manufacturer:
The JSF Joint Strike Fighter program was set up to develop a new "all-weather" multi-role fifth-generation fighter that could be a valid replacement to the current ground attack aircraft of the United States and NATO. The single-seat Lockheed Martin F-35 Lightning II aircraft was born from the project. Equipped with an innovative technology, it is distinguished by the adoption of an aerodynamic layout, with stealth characteristics and a trapezoidal wing. Designed to carry out missions of air supremacy, close air support and ground attack, its cell is available in various configurations.
This is a CTOL (Conventional Take Off and Landing) version. Includes photo-etched parts and Japan Air Self Defense Force decals, as well as further decals for 6 other versions.
