Israel (1948-1949)
Fighter – 25 Purchased 

The Avia S-199 was a post Second World War fighter produced in Czechoslovakia. A total of 532 airplanes of different versions were built and used by the Czechoslovenské letectvo (Czechoslovak Air Force) from 1947 to 1955, and 25 planes were used by the Israeli Air Force (IAF) of the newly formed State of Israel between 1948 and 1949.

After the Second World War, the fate of many European Jewish survivors of the Holocaust was bleak. Some returned to their homes across war-ravaged Europe, starting their lives from scratch. Others, who had lost entire families in the concentration camps or had lost everything for the war, decided to move to Palestine to establish the State of Israel.

Many of these, however, were blocked at the border of Palestine by the British, who were worried that the thousands of Jewish migrants could overrun the region. Others still ended up in British camps for displaced persons in Cyprus.

Some World War II veterans of different nationalities, Jewish or not, decided to take matters into their own hands. One such person was Lou Lenart ,who had lost 14 relatives in concentration camps, who wanted to retaliate and help displaced persons by joining the Haganah, an Israeli military organization, and becoming a so-called ‘Mahal’ ,Mitnadvei Hutz LaAretz’ or “volunteer from abroad”. During the Independence War, the Mahal numbered about 3,500 persons from 58 different countries. At the start of the hostilities, of the 18 fighter pilots of the Haganah, 15 were Mahal.

Czechoslovakian Necessity

After World War Two, Czechoslovakia had a shaky democracy dominated by communists, many of whom were of Jewish descent and pro-Zionist, despite discrimination and oppresion of Jewish people by the Soviets.

Czechoslovakia had found itself in possession of a large quantity of German weapons, many of which had been produced under occupation within its borders. Some types remained in production after the war ended with raw materials left in warehouses and factories or surrendered by the Anglo-Americans.
The Czechoslovakian arms stockpile would continue to grow as its soldiers returned, often with foreign supplied weapons.

Czechoslovakia was looking for a way to restore its economy, which was at an all-time low after the German occupation and the destruction caused by the war. Selling weapons was an excellent way to do this.

Mutual Aid

The Czech delegation to the UN voted for a Jewish state only a few months before a communist coup turned Czechoslovakia into a Soviet satellite state. Czechoslovakia then became one of the most important partners in helping arm the Jewish people.

Surplus German and Czech arms from World War II were purchased by the Czechoslovakian government and shipped to Palestine. Not only did they provide light weapons, but the country became a center for all forms of material aid.

While light weapons were important, the Israelis needed tanks and an air force to counter neighbouring Arab armies. All of this aid incurred a huge financial burden for the Czechs. Joseph Stalin allowed support to continue after the Czechoslovak communist coup, not so much as to support the Israelis, but to undermine the British Empire. The first contract was signed on January 14th, 1948 by Jan Masaryk, the Czech foreign minister.

The contract included 200 MG 34 machine guns, 4,500 K98 rifles, and 50,400,000 7.92 x 57 mm Mauser rounds for these rifles and machine guns.

Syria also purchased a quantity of weapons from Czechoslovakia for the Arab Liberation Army, but the shipment arrived in Israel due to the intervention of the Haganah.

After the communist coup in Czechoslovakia in February 1948, military support for the nascent state of Israel increased temporarily. However, Stalin’s brief policy of support for the state of Israel soon faded, and in the wake of the Tito-Stalin split, all Communist parties had to put their foreign policy on par with that of the Kremlin in order to prove their loyalty. In this context, the Czechoslovakian communists put an end to arms sales to Israel.

The first shipment of 200 rifles, 40 MG 34 machine guns and rounds landed secretly on the night of March 31st-April 1st 1948 at an improvised airport in Beit Daras on an American Douglas C-54 Skymaster cargo plane. The second larger shipment, covered with onions and potatoes, consisting of 450 rifles, 200 machine guns and rounds, arrived at the port of Tel Aviv aboard the merchant ship Nora on April 2nd, while a third shipment of ten thousand rifles, 1,415 machine guns and rounds reached Israel by sea on April 28th. Finally, the Haganah command had a stockpile of thousands of small arms on hand, but, as mentioned, other equipment was also needed to create an air force and armored units.

The Aircraft

In the final phase of the Second World War, it was decided that the factory of the Avia company located in Prague-Cakovice would assemble the Messerschmitt Bf109G-6, Bf109G-14 fighters and the Bf109G-12 two-seater trainer aircraft for the needs of the Luftwaffe. This production was based around components supplied by German factories.

After the war, a large stock of remaining spare parts was left and it was studied, along with the original blueprints, by the new authorities in order to begin local production of the aircraft. With the remaining spare parts, some aircraft were assembled, but there was a shortage of engines.

On 31st July 1945, at about 15:30, the ammunition depot at Krásný Březno exploded, killing 27 people and injuring several dozen more. The explosion and subsequent fire destroyed the depot, including the chemical plant buildings. The explosion was interpreted as being a result of sabotage carried out by the local Germans. In retaliation, the locals carried out the Ústí Massacre, killing about 80-100 ethnic Germans.

In addition to munitions, the warehouses that exploded also contained almost all Daimler-Benz DB 605 engines available in Czechoslovakia.

As a result, the Czechoslovak Air Force had to equip the aircraft with the Junkers Jumo 211 F-12 engine ,produced in Czechoslovakia as M-211F, of which there were several left after the war.

The Jumo 211 was not very suitable for installation on fighters, as it was originally intended only for bombers, such as the Heinkel He 111, Focke-Wulf Ta 154 and Junkers Ju 87. It was less powerful and heavier than the Daimler-Benz DB 605 engine, at 720 kg and 1,350 hp versus the DB 605AM’s 700 kg and 1,775 hp (on the Bf109G-14 variant).

In addition, the Junkers engines did not provide for the installation of synchronizers, so it was necessary for the Avia engineers to modify them to synchronize the turn of the propellers with the aircraft’s guns, and create a new propeller. The first Avia S-199 fighter ,C-210, took off on April 25th, 1947 from Prague-Kakovice airport, flown by test pilot Petr Široký. After solving some mechanical problems, the series production of the machine began almost immediately.

The Avia fighter differed from the original Messerschmitt Bf.109 only in terms of propulsion and armament. Because of the new engine, the engine cowling, propeller, and spinner were modified.

The armament of the S-199 consisted of two 13 mm Mauser MG 131 machine guns with 600 rounds above the engine, and either two 7.92 mm machine guns in the wings or two 20 mm MG 151 cannons mounted under the wings in gunpods.

Because of the new engine, the Czechoslovakian aircraft was inferior to the German Bf 109 G-10. The maximum speed of the S-199 was 590 km/h compared to 690 km/h of the Messerschmitt. The maximum altitude was 9,000 m compared to 11,000 m. The worst problem was the change in the center of gravity of the aircraft, which greatly complicated takeoff and landing.

The S-199 had another serious defect: the machine guns placed under the engine hood were not always synchronized with the propeller, which led to serious accidents.

Several plants were set up for the production and assembly of the Avia S-199, the Prague Automobile Plant, Plant No. 2 of Avia, and the plants of the Aero company where they assembled the aircraft. Rudders and ailerons were supplied by Letecké Závody in Letňany. The Letov company in Malešice produced the M-211 engines and the propellers and spinners were manufactured in Jinonice.

A total of 450 S-199 single-seaters and 82 CS-199 two-seaters were produced for training purposes, of which 24 were later converted from single-seater fighters.

First Aircrafts

The Czechoslovaks helped create the Israeli Air Force by selling the nascent Israeli state 25 Avia S-199 fighter planes in 1948.

The agreed cost was 180,000 USD (~2 million USD adjusted for inflation) per aircraft, including armament, ammunition, spare parts, pilot training and support equipment. This was a disproportionate price for what was, by now, a mediocre aircraft. At that time, an American surplus P-51D Mustang was sold second hand for only 4,000 USD (~44,000 USD adjusted for inflation).

Unfortunately, due to the embargoes imposed on Israel, it would have taken weeks or months to find other offers, time that Israel did not have given the conflict with the neighboring Arab states. A few weeks could make the difference between destruction and survival for the new state.

David Ben Gurion, the Prime Minister of Israel, did not hesitate and gave the order to buy the planes and to send the pilots to training as quickly as possible. A contract was signed for 25 Avia S-199 at a total cost of 4.5 million USD (~50 million adjusted for inflation).

Pilot Training

The first 10 Israeli pilots departed from Sde Dov on 6th May 1948 and arrived at the Czechoslovakian air base in České Budějovice on May 11th, 1948. Of the 10 pilots, 2 were US volunteers and one was South African, these last three were veteran pilots of the Second World War, having served with the US Army Air Force and Royal South African Air Force respectively. The other seven were British or Palestinian Jews, some of which were World War II veterans, while others had only completed Royal Air Force training in Rhodesia in early 1945, failing to actively participate in World War II.

The first to fly the Czechoslovakian fighter was former Marine Corps pilot Lou Lenart. As soon as he started to gain speed, due to the larger propeller, the aircraft started to yaw to the left. He was aware of this problem but he was likely unable to do anything about it.

When he returned to the runway, he managed to take off after several attempts, having to fight against the plane to avoid going off the runway. After a few minutes, he returned to the airfield and the pilot again had to fight to keep the plane straight during landing.

When all 10 pilots made their first flights, they gave their impressions of the plane. None were positive. The landing gear was narrow and made the S-199 difficult to keep straight during take off due to the huge torque of the propeller. The plane was unwieldy and very hard to handle, the cockpit was cramped and the canopy was hard to open.

The Jewish volunteers discovered that the Czech pilots called the S-199 ‘Mezec’, which means “mule,” and they quickly understood why.

The Jewish volunteers were accustomed to spacious, agile and fast Allied fighters, such as the Spitfire, P-51D Mustang and P-47 Thunderbolt. The shock of flying an aircraft with completely different characteristics upset them, but the Avia was all they had and they had to make do.

After only 4 days from the beginning of the training, on May 15th, the pilots of the Sherut Avir, Air Service in Hebrew, the ancestor of the Israeli Air Force, were recalled to Israel.

During training in Czechoslovakia, only five of the volunteers, those with World War II experience, had qualified to fly the Avia and none had flown it more than twice. The first S-199s were disassembled and loaded, along with other equipment, onto a Douglas C-54 Skymaster named Black-5. This plane landed on May 20th, 1948 at Be’er Tuvia, 40 km south of Tel Aviv, with the first disassembled Avia S-199, some bombs, Avia’s machine-gun rounds for the aircraft’s guns, artillery spare parts, and five fighter pilots who had “completed” their training in Czechoslovakia, American Lou Lanart, American Milton Rubenfeld (former RAF and USAF), South African Eddie Cohen (former RAF), Israeli Ezer Weizmann (former RAF) and Israeli Mordecai ‘Modi’ Alon (former RAF).

On the night between 23rd and 24th May 1948, one of the Douglas C-54 Skymasters carrying the fifth Avia for the fifth pilot crashed during landing due to poor visibility. The navigator, Moses Rosenbaum, died crushed by the fuselage of the Avia S-199 they were carrying, while the other three crew members were only injured.

Some sources report that the number of Avia S-199s that arrived in Israel was only 24. This could be a simple error or it could mean that Czechoslovakia delivered all the Avia but that the one that crashed on the night of May 23rd, perhaps because of the damage suffered, could not fly anymore and was used for spare parts.

Operational Use

The Israeli Air Force gave the Czechoslovakian fighter the nickname “סכין”, meaning “knife” in Hebrew. After being reassembled, the aircraft received the Israeli air force’s coat of arms and a number ranging from 100 to 125 for identification.

After the outbreak of hostilities, the war was going badly for the State of Israel, which had been invaded by anArab force composed of Egyptians, Syrians and Iraqis with the support of other nations such as Jordan and Lebanon. The Egyptian Army was advancing north along the Mediterranean coast, arriving less than 30 km from Tel Aviv.

Despite the fact that the Israeli engineers of the Givati Brigade had blown up the bridge over the Lachish river, the Egyptians continued to amass along the south bank of the river. It would take them a few hours to repair the bridge and they could arrive in Tel Aviv during the next day.

That evening, the last phases of the assembly of the first four aircraft had been completed in a hangar. An attack was being organized for the following days against the Royal Egyptian Air Force airport in El Arish, in order to take the REAF by surprise and announce in a very daring way the existence of the IAF.

Due to the proximity of the Egyptians to Tel Aviv, the Israeli pilots were ordered to take off with the only four S-199s that had arrived from Czechoslovakia. The planes had not yet been tested in flight, not all four had radios and those that had them did not work. The guns had never been tested, not even during the training of the pilots, who had flown on these fighters only twice.

The four S-199s, piloted by Lou Lenart, Ezer Weizman, Modi Alon and Leonard Cohen, took off one hour before dark. Lenart, who commanded the unit, had never flown in Israel before, and he did not know where Ashdod, which was less than 15 km away from their airport, was located.

Anachronistically, he gestured to the other pilots the direction to go. Having clarified the direction to go, there was another problem, as the villages along the coast looked similar. Fortunately, columns of smoke were seen and, shortly afterwards, a column of Egyptian trucks and light armored vehicles was spotted stretching for more than a mile south of the Ashdod bridge. These belonged to engineering units trying to repair the bridge for the forces that were to take Tel Aviv the next day.

The pilots of the four planes attacked the column, which immediately dispersed. The Egyptians were not aware of the existence of an Israeli air force, lacked sufficient anti-aircraft weapons and, in some cases, had never seen an aircraft before.

The fighters swooped down on the Arabs, dropped the two 70 kg bombs they had and started to strafe the scattering soldiers. After a few shots, the guns jammed. In reality, the bombs and the following machine gun strafing did little damage. However, the psychological impact on the Egyptian troops was so devastating that, the next day, the order to attack Tel Aviv was cancelled. After that, the Egyptian offensive strategy became purely defensive.

During the attack, South African Leonard ‘Eddie’ Cohen’s Red Four plane was shot down by anti-aircraft fire. Cohen was the first loss of the Israeli Air Force. During landing, Modi Alon’s Red Two aircraft went off the runway and was damaged.

At 0530 hrs on May 30th, in order to take advantage of the surprise appearance of the IAF, the two remaining S-199s, piloted by Weizman ,Red 1, and Milt Rubenfeld,Red 3, attacked the village of Tulkarm in northern Israel, which controlled by a Jordanian-Iraqi force.

In this case as well, the real damage was insignificant but the psychological effect was devastating. A bomb had hit the police station where the Arabs were hiding themselves and 4 tanks were machine-gunned.

Rubenfeld’s plane was hit, probably by two anti-aircraft cannon shots, one in the wing and one in the fuselage. Due to the damage sustained by the aircraft, he could only return to the territory controlled by the Israeli Defense Force and then bail out at low altitude into the sea. He jumped from about 370 meters, but the parachute did not open properly and he fell into the water and was injured. He swam towards the shore, andafter two hours, he realized that the water in which he was swimming was very shallow and he had reached land.

He became the target of rifle shots from a nearby kibbutz, being mistaken for an Arab pilot ,the Israeli Air Force had remained a secret until the day before. He was then rescued and, after treatment, brought back by cab to Tel Aviv and then returned to the United States.

On May 30th, the unit was officially named the 101st Squadron or First Fighter Squadron, a name that was very impressive for a unit that had two fighters, one of which was operational, and four pilots, one of which was wounded.

On June 3rd, 1948, two Douglas C-47 Dakotas, escorted by two Egyptian Supermarine Spitfires, arrived from over the sea to bomb Tel Aviv. This practice had been ongoing for a long time and had cost the lives of hundreds of civilians in the city. The Egyptian tactic was to drop bombs out the back door onto the city below.

That day, late in the afternoon, 101st Squadron was alarmed that the Egyptian bombers were again on their way to Tel Aviv. Modi Alon took the only available S-199 and took off.
Arriving in the skies over the city, he spotted the two C-47s with two Spitfires escorting them.

Modi Alon first flew west over the Mediterranean Sea, thus being able to approach with the sun behind him. The enemy aircraft would thus have a hard time seeing him, a tactic RAF instructors in Rhodesia had taught him.

Arriving behind the first C-47, he hit it with a long burst of cannons and machine guns and sent it crashing to the ground. With a very risky maneuver, he passed in front of a Supermarine Spitfire and then turned around again to attack the second C-47 head-on.

The slow and clumsy Douglas tried to turn around to get rid of the attacker while the two Spitfires tried to line up the Avia, trying to hit it to defend the bomber.

Alon’s S-199 shots hit the second C-47, which crashed into the Mediterranean shortly after. Alon then pushed the throttle to full and sped away at top speed, without the Spitfires being able to hit it.

On June 8th, 1948, during his first mission aboard an S-199, Gideon Lichtman, who had trained for only 35 minutes aboard the Avia, flew the first dogfight of the war against an Egyptian Spitfire that was strafing civilians in Tel Aviv.

Lichtman didn’t even know which trigger to fire, so he kept pressing buttons, levers and switches until he found the right one, and chasing one of the Spitfires, he opened fire, shooting it down. The U.S. pilot was forced to land without fuel because he had only 40 minutes of fuel when he intercepted the enemy plane.

Exactly one month later, on July 8, (some other sources claim 18 July) Modi Alon left with other 2 Avias to attack an Egyptian reinforcement column at Bir Asluj in the Negev Desert.
After the successful attack, on their way back Alon noticed two Egyptian Spitfires Mark VCs in flight, attacked them and managed to shoot down one of them which was the one of the Wing Commander Said Afifi al-Janzuri.

Although the career of the few Israeli Avias seemed good, due to its poor handling characteristics on the ground, no more than four planes were operational together, recalled pilot Mitchell Flint, veteran of the Pacific Campaign.
On the morning of July 9 Lou Lenart was ordered to attack the Egyptian air base of El Arish with four fighters. The fuel was low and the tanks could not be filled to capacity.
During takeoff the Avia S-199 number two piloted by ex-USAF aviator Stan Andrews swerved to the left during takeoff, flipped over and blocked the runway for 15 minutes causing the other fighters to consume fuel.

The three remaining operational S-199s running out of fuel hit the much closer Egyptian-controlled Gaza port.

Only two S-199s returned to base while the third, piloted by former USAF Bob Vickman, had not returned. Despite efforts Vickman was never found again.

The next day there was a similar situation, a pair of S-199s attacked two Syrian bombers near the Sea of Galilee. Ex-RAF pilot Maury Mann, shot down one of the two bombers within seconds while his South African ex-RAF wingman Lionel Bloch , in aircraft 108 .ד‎, attacked the second one chasing it as it retreated into Syria.That was the last time Bloch was seen, neither he nor his S-199 returned to base.

The next morning Sydney ‘Syd’ Cohen, a former South African medical student, member of 101 Squadron and future leader of the squadron, took off to search for Bloch or the remains of his plane.

Syd had spent more time training in Czechoslovakia so he realized that there was something wrong with the disappearance of two planes in two days, he acted on instinct and fired a very short burst with the machine guns mounted in the engine cowling.

When he landed, everyone noticed that all three propeller blades had bullet holes in them. The synchronizer was faulty, Vickman, Bloch and some thought also Leonard Cohen had all likely shot their own propellers while firing their guns.

On October 16, 1948, Airman Rudy Augarten, a former USAF pilot who had shot down two Messerschmitt Bf.109s during World War II, was on a reconnaissance mission over El Arish Air Base, which had been attacked the previous day. As he flew south toward the coast in the distance, he saw two Spitfires flying in formation.

Augarten followed the two Egyptian planes, trying not to be detected.
Augarten lined up with one of the Spitfires and fired a burst, sending the Egyptian plane plunging toward the Israeli lines. The other Spitfire, pursued by Augarten’s wingman Leon Frankel, fled the battle.

That same day Alon and Weizmann departed at 1658 hrs for a mission near Ashdod where both had done the first IAF mission. After the success of the mission Alon had returned and during the approach to the runway he reported by radio that he had a problem with the landing gear, a common problem on Avias that was never solved. One or both of the pistons that lowered the struts would not extend fully. The Israeli pilots learned the hard way that they had to pull the nose of the fighter up and down to get the landing gear fully retracted into the wing.

While Alon was working out his problem, observers on the ground noticed something more troubling. A trail of gray smoke was coming out of his fighter’s nose.
Alon was told over the radio to check the temperatures of the plane’s various gauges. “They were fine” Alon replied seconds before his fighter crashed in flames next to the runway, killing him. His daughter born 6 months later could not meet him but served in the same squadron as her father.

From that moment on, the Avia S-199 were more and more rarely used by the Israelis.
Very few of them were still operational and, starting from September 25, 1948, about fifty ex-Czech Supermarine Spitfires IX were arriving in Israel, which would have been much more reliable.
The S-199 fighters flew with the Coat of Arms of the Israeli Air Force until June 1949.

The aircraft maintained the Czechoslovakian sand coloration but the Israeli Air Force coat of arms (Stars of David) were applied in light blue on a white circular background on the sides of the fuselage and on the wings, top and bottom.

During the first missions the Stars of David were painted without paying attention to size, but later they were painted in standard size. Behind the David’s Star there were three bends white-light blue-white and the Israeli identification number, from 100 .ד‎ to 125 .ד‎.

In front of the propeller nosepiece (which was painted red or blue in some cases) was painted the 101 Squadron coat of arms, a skull with wings inscribed in a red circle.

From September 1948 the rudders were painted with red and white oblique lines but photographic evidence shows that not all aircraft received them, at least until December 1948.

At least one aircraft, towards the end of the war, was painted in two-tone camouflage, dark brown and sand yellow with the underside of the aircraft in Mediterranean blue.

Conclusion

The Avia S-199, although an extremely unreliable aircraft, was the first aircraft of the Israeli Air Force, the only one that at that time they could acquire due to UN embargoes.
During the 13 months of IAF service the Israeli pilots shot down a total of 8 Arab aircraft without losing a single Avia to Arab aircraft.
The major losses were due to mechanical problems of the aircraft leading to the conclusion that the Avia S-199s were more dangerous for the Israeli pilots than for the Arab pilots.
