"Pretty cheap price for one of the most famous Flankers, huh? Of course it's not a knock-off. This special price is just for you."
Harry's description of this plane in the shop.

The S-55 LFS, referred to as the S-55 Flanker O in the PAL version of Airforce Delta Storm, is a plane that has appeared in the PAL version of Airforce Delta Storm and all versions of Airforce Delta Strike. It is a concept-plane made for the LFS project, developed from the S-54 trainer aircraft. However, the project was cancelled in favor of the PAK FA program. The I-2000 LFS was also spawned from this project, which also appears in this game series.

Design (All Games)

As to be expected, the S-55 LFS looks very similar to the Flanker family. However, there are some major differences. Firstly, the plane has a smaller build than the Flankers. And secondly, it only has a single engine, as opposed to two, which most likely owes to its somewhat lower thrust and speed.

Performance

Airforce Delta Storm

This plane is interesting in that it is one of a few PAL-exclusive aircraft. Stats are fairly average; it has good Mobility and Defense stats, but other stats are average. It has a decent amount of armaments and a fairly high range. It's also unlocked fairly late in the game, at the same time as the YF-26ER Swan. Then again, considering the Swan was nerfed in the PAL region, this plane may be slightly more worth it compared to the latter.

Airforce Delta Strike

The plane is quite similar to its AFD Storm incarnation, though defense has been nerfed a good bit. It also now has a special weapon in the form of the HM-AAM. It has decent mobility and anti-air stats, but other stats are average. It is unlocked the same time as the MiG-1.44 MFI, with the same requirement of completing ten missions as Ken Thomas.
