The Nordfluss KFZ-7 Boxfalke is a Vazandian all-weather multirole strike fighter. The KFZ-7 was designed in the 1960s and 1970s for long-range, high-speed Air interdiction without relying on escort or electronic-warfare aircraft. Luftwaffe (KRL) KFZ-7 Boxfalkes are the primary multirole aircraft employed by Vazandia

The Boxfalke has been deployed for military operations in numerous nations around Atlas. During these operations, the strike fighter has carried out deep strikes against high-value targets and combat air patrols, and provided close air support for Vazandian troops. It has also been exported to several countries.



The KFZ-7 was introduced by the KRL to replace its fleet of KFZ-13 Weisserrabes. Unlike the KFZ-13, the KFZ-7 was designed for the air superiority mission with little consideration for a ground-attack role; the Armed Forces Budget Office opposed the idea of KFZ-7s performing the interdiction mission. In service, the KFZ-7 has been a successful fighter, scoring numerous aerial combat victories and minimal losses in air-to-air combat as of 2020.

Despite a lack of official interest, Nordfluss quietly worked on a KFZ-7-derived interdictor fighter. The company envisaged the aircraft as a replacement for the EFZ-49 Fanatiker and the remaining KFZ-13s. In 1979, the KRL initiated a year long trial, which looked at Nordfluss' proposal and other options such as the purchase of further EFZ-49s. The study recommended the KFZ-7 as the KRL's future strike platform. In 1980, Nordfluss and Stettinwerke AG began a close collaboration on the development of the KFZ-7b's air-to-ground capabilities.

To assist in the KFZ-7's development, Nordfluss modified the second ExKFZ-7 prototype as a demonstrator. The aircraft, known as the KFZ-7b, first flew on 8 July 1982. It was previously used to test conformal fuel tanks (CFTs), initially designed for the KFZ-7. It was subsequently fitted with a laser designator targeting pod to allow the independent delivery of guided bombs. The demonstrator was displayed at the 1982 Altstadt Airshow.

Operational history[edit]



KFZ-7a: Original variant adopted by the Luftwaffe- all airframes exported or upgraded to 7c.

KFZ-7b: Upgraded variant that entered service in 1989.

KFZ-7bA: Dedicated training aircraft introduced in 1990.

KFZ-7c: Heavily modernized variant introduced in 2003 and in production up until 2015

KFZ-7ZK Slam Falke: The KFZ-7ZK Slam Falke is a derivative of the KFZ-7, operated by the Republic of Ziridava Air Force. The ZK variant has several features not typically found on KFZ-7, such as the VolgEye Infra-red search and track, a customized Tactical Electronics Warfare suite to reduce weight and increase jamming effectiveness, cockpit compatibility with night vision devices, ARC-232 U/VHF radio with Fighter Data Link system, and advanced SR/A-115 active electronically scanned array (AESA) radar. The KFZ-7ZK is equipped with the Joint Helmet Mounted Cueing System and can be equipped with the SB-92 and SB-07 anti-ship missiles.

KFZ-7/Sa Schlagfalke: 2-seat strike variant developed to supplement and eventually replace the RFZ-5 Möwe.

KFZ-7/SaU: SEAD-focused platform variant of standard 7/Sa.

KFZ-7/Sb: Improved strike variant meant to fully replace the RFZ-5 by 2022.

KFZ-7/SbU: Improved SEAD variant.

KFZ-7/Ma: Twin-seat variant based off the KFZ-7/S Schlagfalke.

KFZ-7/Mb: Improved version of 7/Ma
