Short History: In 1941. there was a project about improving performance Rogozarski IK-3 fighter by instaling a more powerfull engine. Out of 3 engines considered stronger Hispano Suiza V12 engine became unavailable because of Fall of France so two other options were Rolls-Royce Merlin III engine and Daimler Benz DB 601Aa. So to test which one is better they took one Hurricane and replaced Merlin engine with the DB 601 one.Then they tested performance of standard Hurricane against modified one named LVT-1. LVT-1 was superior in every aspect and DB 601 engine also allowed instaling a 20mm motorcannone. Test were succesfull and all IK-3s in production would receive DB 601 engine replacement if it was not for worsened relations between Yugoslavia and Germany which would result in Axis invasion.

 

Operational history: Even though it was a test aircraft, good performance it performed and no failures with new engine promoted LVT-1 in operational service. LVT-1 actually was involved in first aerial combar in the war. In the first day of the war, April 6th 1941, LVT-1 pilot intercepted a BF-110 on a reconaisance mission and forced him to land in Kraljevo. That BF-110 would be used later in the war by the Royal Yugoslavian Air Force in defence of the country.Day later LVT-1 intercepted some German fighters and was heavilly damaged and forced to land somewhere in Kosovo region of the country. Faith of the plane after that is unknown.

Notes
 

This is pretty incomplete data sheet but it is only from one source so it would be great if we could find another one. Overall it would be great tier 2 premium plane sitting at around 3.0 BR. It is very interesting combination of two different designs, and it would be pretty crazy to fly pretty quick Hurricane while hearing the sound of BF-109 engine :D. Aircraft has good performance and excelent armament for its tier so it would be very competitive.
