FS-17B Tyrfing fighter concept

A guest from a parallel universe, where during WWII Nazis were the first ones to create nuclear weapons. At March 1945 they launched a nuclear attack on every major city in the USSR and other Allied nations. While it did not stop the fall of the Axis nations, by 1950 USSR, USA and Europe were all torn apart by multiple internal conflicts into dozens of small “sovereign nations”. 

In 1952 a group of VVS and USAF veterans proposed a creation of military/political force, that aimed to restore the pre-war nations to their former glory. That was the beginning of the Hammer Foundation. The Foundation took great effort to acquire most materials and personnel of WWII-era science facilities and construction bureaus.

As the Hammer Foundation face multiple enemies, from Nazi revanchists to biological terrorists it need to keep on edge of military power. In 1967 the contest for the new naval aircraft was announced. The winner was S-10, an aircraft created by members of former Grumman and Sukhoi companies. It took first flight in 1969 and by 1970 was actively supplied to the Hammer Foundation Red Cell as FS-17 (HF is spilt administratively into ten “cells”, which are color-coded. For example Red Cell is a military branch, Black Cell is intelligence, Blue Cell handles all Science-related matters). As the aircraft is highly upgradeable, there’s no plans on retiring it until 2060s. 

FS-17 features two AF-110F engines, variable wing geometry and large internal fuel tanks. It’s a carrier-based aircraft designed to achieve air superiority over both sea and land. It uses AN/APG-71 radar along with OEPS-27 (OEPS-27M on FS-17B and later variants) electro-optical targeting system.
