The NA48 Chainbreaker (Takelat: ⵏⴰ48 ⵔⴰⵣⴰⵜⵉⵙⵦⵏⵙⴰⵍⴰⵏ; NA48 Razatisensalan) is a twinjet, canard, delta-wing, multirole combat fighter. The Chainbreaker is generally classified as a 4.5++ generation aircraft, and occasionally as a heavy multirole fighter as It is equipped with advanced sensors and avionics with limited stealth design and is capable of engaging in supremacy, interdiction, reconnaissance, close air support, and anti-ship warfare missions.

Developed from the NA28 Spirit Wind, the Chainbreaker was intended to consolidate the roles of the NA28 Spirit Wind and the NA28/36 Sunray in a modern platform. The airframe first flew in 1998, but the development of the aircraft's systems delayed its official introduction to 2004. While primarily a domestic project, the full avionics and sensor suite was developed with a number of foreign resources and technologies.

Following its introduction, the Chainbreaker was marketed for export to a limited number of socialist republics worldwide. The Talaharan Air Corps remains the primary user of the aircraft, in addition to the Tyreseian Workers' Naval Air Service.

Development

The NA48 Chainbreaker was developed from the single-engine NA28 Spirit Wind and shares a considerable number of commonalities with the older aircraft. Despite this, the Chainbreaker is considerably larger and heavier than its predecessors. The design of the airframe was completed in the mid-1990s and production began in 1997. The first test flight took place in May of 1998. After its success, full production of the airframes was commenced that year, though the aircraft was only officially brought into service after the sensors and avionics were successfully selected and installed in 2004.

Origin

After the introduction of the NA28/36 Sunray in 1986, the Talaharan Air Corps relied on three different mainline fighter aircraft, including both variants of the NA28 and the aged NA6 Tiara which had originally entered into service in 1961. By 1990, the Talaharan Air Corps was preparing for the retirement of the Tiara and were seeking to adopt a new modern fighter aircraft with superior multi-mission capabilities and at least some limited stealth design elements for the new millennium.

The United Aeronautics Syndicate received its commission for the project, dubbed the "X50 Fighter Program", later that year from the TCDF Air Corps Logistics and Design Commissariat and an internal tendering process within the Syndicates design bureau was commenced following Tyreseian endorsement under the Rubric Coast Joint Development Agreement. Reportedly, four designs were evaluated, including wind tunnel testing, at a scale model phase. However, only one design made it to the full prototyping stage to be presented to the Logistics and Design Commissariat in 1997. This prototype from Design Bureau B - Weskera ultimately underwent multiple revisions before first taking flight a year later. The X50 would subsequently be renamed the X48BW after the year of its first flight and entered into full production as the NA48 Chainbreaker.

Production

While the United Aeronautics Syndicate began full-scale production of the airframe immediately after receiving approval from the Logistics and Design Commissariat, the delivery of the planned avionics and sensor suite of the final aircraft was initially delayed owing to the number of parts of devices that had to be sourced from Tsurushima and Wazheganon. As such, the production chain for the aircraft was only finalized in 2003, with the Chainbreaker officially entering into active service with the Talaharan Air Corps in 2004.

Production of the airframes is handled primarily at the United Aeronautics Syndicate Manufactory in Wasif. The avionics suite is assembled domestically at the port of Mutafayil, with a number of components still produced overseas. The avionics suite is subsequently shipped for final installation in Wasif.
