In
early 1938 the Yugoslavs ordered 12 aircraft. The first two were ferried
by air via France and Italy to Yugoslavia on 15 December 1938. The
aircraft had Merlin II engines and two-bladed Watts Z.38 propellers. The
remaining ten aircraft were not delivered until April 1939. Most
probably the first 12 Hurricanes received serials in the range
BR.2301-BR.2312. All Hurricanes of the first batch had their two-bladed
Watts Z.38 propellers replaced by three-bladed de Havilland Hamilton
type. These changes were introduced by April 1941.
After WW2 broke out
the British sent another batch of 12 aircraft. These were the Hurricanes
with all-metal wings, Merlin III engine, and three-bladed de Havilland
Hamilton propellers. Deliveries started in February 1940. The aircraft
reached Yugoslavia in March 1940. Most probably they received serials
from BR.2313 toBR.2324.
In early 1940 a license agreement for Hurricane production in Yugoslavia
was signed. The government ordered 100 Hurricane Is. The Fabrika
Aeroplana i Hidroplana at Zemun "Zmaj" was going to make 60, and the
Rogozarski, a further 40 aircraft. By the time of the German invasion
Zmaj completed the first batch of 24 aircraft. Most probably 18 machines
were delivered to air units before 6 April 1941. These were aircraft
with Merlin III engines and de Havilland Hamilton propellers. The
remaining 6 aircraft would reach military units after the war with
Germany started. Aircraft made by Zmaj had serials BR.2325 to BR.2348.
The other factory to make Hurricanes was Rogozarski. In April 1941 12
machines were nearing completion (fully assembled they awaited delivery
of propellers and machine guns). Another similar batch was at various
stages of preparation for assembly. There is nothing to prove that any
complete aircraft left that factory. The outbreak of WW2 led to
shortages of Merlin engines that were not supplied by the British in
required numbers. In an attempt to overcome this, Yugoslav engineers at
the Ikarus "Zmaj" factory at Zemun tried to replace the British engine
with the German Daimler-Benz DB601 A. This task was entrusted to two
designers: Ljubomir Ilic and Kosta Sivcev. The British engine was
removed from one aero plane, and replaced with the German one. Such aero
plane underwent testing in March 1941. The pilot, kapeten I klase Milos
Bajagic, and others, flew a total of some 100 hours in it. This aircraft
was designated LVT-1 (Lovac Vazduhoplovno Tehnicki -1 - Technological
Air Fighter). Use of the new power plant significantly improved the
performance of the Hurricane, it was 20 km/h (12.4 mph) faster than the
British original. In this connection it would enter production. This was
undertaken by the Rogozarski factory, where fuselages were adapted for
the new engine. The first batch of aircraft was 87 per cent complete on
6 April 1941.
