With the Salamointi serving a magnificent role in its air defense role over Finland against its Soviet aggressors and the subsequent invasion of the Soviet Union, it was believed that it was only a matter of time before the Allies would begin a wide scale bombing campaign on continental Europe, most likely through a landing in Africa, the Soviet Union (Before its fall,) large scale carrier attacks or if the allies gained a foothold in the UK. Were it via carrier, the VL Salamointi and the IVL Norppa ( @Oni789 's design) were believed to be more than sufficient to deal with the threat of carrier based attackers. However the potential of land-based long-range bombers in large numbers attacking from Soviet Airspace, North Africa or the UK was something a high-performance fighter specifically built for bomber interception would be necessary for. Thus license production of the Junkers Jumo J.050 as the LKM L.50 was sought to produce a twin engined jet fighter in conjunction with assistance from Heinkel Flugzeugwerke to tap their experience with turbojets in the early '40s.

Several experimental designs were drafted but only a handful reached prototype stage. One emerged as a conversion trainer that used a single engine configuration but using the outdated Junkers-Jumo J.015. The second formulated with assistance from Heinkel though would be a dyed in the wool bomber killer and this became the VL Tuulenpyörre or Whirlwind in English. Outfitted with twin LKM L.50s (Blasto J50 Turbojets), six MK108 30 mm Auto-Cannons and 14 3 cm Anti-Aircraft Rockets - the new design took on a passing similarity to Heinkel's He-280; Only far more impressive. Capable of achieving speeds of over 912 mph at 30,000 ft - which is Mach 1.34 at those altitudes.

The new fighter was expected to tear into bomber formations that were staggered and stacked and fire for effect with rocket and auto-cannon fire, dive through, circle around and repeat the process - faster than most gunners could possibly train in on their position; Especially when facing multiple aversaries attacking from more than one position.

Unlike the earlier Luftwaffe jet fighters however, this new aircraft demonstrates remarkable maneuverability at medium to low speeds at low altitudes as well. Furthermore the new bomber hunter squadrons work together with Salamointi and Norppa fighter squadrons which cover their approaches and have been training to fight fighter-to-fighter to allow the bomber hunter squadrons to do their work. Furthermore, far from vulnerable at take off, the new aircraft could instantly go into a vertical climb and accelerate all the way to its prime operating altitudes in 75 seconds on the average. A weakness shared with these early jet fighters though is their limited fuel capacity. At low altitudes the new fighter can only operate at peak ability for perhaps 20-30 minutes while at the 25-40 thousand foot altitudes this operation time is extended significantly.

Several new technologies were implemented on the type including air brakes, horizontal trim and jettisonable rocket pods to improve performance rather than retain the fixtures, as prior types in the Luftwaffe had, which created unnecessary drag. While the rockets are a standard armament for bomber interception, auxilliary fuel tanks can be carried in their place for extended operational time.

VTOL slider - Lowers the flaps for take off and landing.
Trim slider - This one is tricky as it is inverted, lift it up to bring the nose up.
AG 1 - Drops the expended rocket pods.
AG 2 - Working in conjunction with trim, the air brakes deploy when the Trim slider is up.

Creator's Notes: I had a heck of a time finding tracer color data for the MK108 Auto-Cannon but I found it buried in the same page I've recommended for others - they're yellow so no changes were necessary there. I have altered the caliber, projectile weight and muzzle velocity for accuracy's sake. The only inaccuracy perhaps is having such a narrow wing root with three of those cannons lined up per wing and the rate of fire should be 6.5 rounds per second vs. the default 7 rounds per second but when I've tried decimals in that spot before it didn't turn out so well so I just left the rate of fire alone. Then again these cannon shells were - well - cannon shells. Some were explosive incindiary while others had hydrostatic sensors that would explode when in contact with any form of liquid - specifically intended to explode in the fuel tanks (and messily enough, the crewmen) of the bombers.

The last matter I wanted to touch on was the use of Trim, Flaps and Air Brakes on landing. Personally I found this to be the easiest jet I've built to date in landing. You can turn the air brakes on and off at will while the trim and flaps working together seem to almost make the plane float in the air. I had fun developing this, and though it was loosely based on an old design, this one turned out much better and proved to be a lot of fun to fly!

@TheMasterSoldier Thank you for building that wonderful B-17G it proved to be a perfect proof of concept for this bomber buster! lol

Finally, this is a fictional aircraft design intended for @General360 's RP.
