There is no Mig-415 Firefly

Flatpack (1.44 MFI) was a technology demonstrator developed by the Mikoyan design bureau. It was the Soviet Union's answer to the U.S.'s Advanced Tactical Fighter (ATF), which gave us the F22. The MiG 1.44 made its maiden flight in February 2000, nine years behind schedule, and was cancelled later that year.
The
LFI project was intended to develop a lightweight fighter with respectable air-to-ground capabilities. Yakovlev proposed the Yak-43. Sukhoi decided to submit a design for the LFI called the S-37 (unrelated to the heavyweight Forward-swept wing fighter). Mikoyan entered the MiG 4.12. MiG could not afford to develop both the MFI and LFI, so their LFI entry was eventually withdrawn.
In 2006, the Russian government merged 100% of Mikoyan shares with Ilyushin, Irkut, Sukhoi, Tupolev, and Yakovlev as a new company named United Aircraft Corporation. Specifically, Mikoyan and Sukhoi were placed within the same operating unit.
JSC United Aircraft Corporation (
UAC) is a Russian open joint-stock company. With a majority stake belonging to the Russian Government, it consolidates Russian private and state-owned aircraft construction companies and assets engaged in the manufacture, design and sale of military, civilian, transport, and unmanned aircraft. The holding encompasses Irkut, Mikoyan, Voronezh Aircraft Production Association, Sukhoi, Ilyushin, Tupolev, Beriev and Yakovlev. It has also been recently announced that the TAPO factory, in Tashkent, Uzbekistan, may also become a subsidiary of the group.
"Russia will partner with the United Arab Emirates to jointly develop a new lightweight fifth-generation fighter in roughly the same class as the Mikoyan MiG-29 Fulcrum. It is clear that the Russian side will carry out most of the substantive development work. It’s not clear what the final configuration of the new fifth-generation aircraft will look like. Rostec chief Sergei Chemezov told TASS’ Russian-language service that the new fighter would be developed from the Soviet-era MiG-29 Fulcrum, but head of the United Aircraft Corporation Yuri Slyusar said that no decisions had been made on the configuration of the new jet. The RSK-MiG—which along with Sukhoi is part of the United Aircraft Corporation—is already working on a privately funded venture to develop a fifth-generation MiG-29 replacement. It is likely this Russian joint venture with the UAE is part of the same project."

"Russia’s RSK-MiG is working on a new lightweight fifth-generation stealth fighter to replace the Mikoyan MiG-29 and MiG-35 Fulcrum series fighters. Called the
Liogkiy Mnogofunktsionalniy Frontovoi Samolyet (LMFS)—or Light Multi-Function Frontal Aircraft in English—United Aircraft Corporation is developing the new aircraft out of its own funds.
Only time will tell if Russia and RSK-MiG can shepherd the LMFS into production. Developing a fifth-generation fighter is a long and expensive endeavor as the Sukhoi is discovering with its T-50 PAK-FA air superiority aircraft.
