T.553 Konge

The T.553 Konge is a twin-engine tactical transport featuring a cargo hold, a rear-access ramp beneath an upswept tail, a high-mounted wing and turboprop engines. The T.553 is designed to perform cargo and troop transport duties, aerial delivery of supplies and equipment and is designed to be compatible with international railway loading gauges to simplify cargo logistics and loading. In flight the cargo area is pressurized and kept at a constant temperature by integrated air conditioning systems.

Additionally, the landing gear can be partially retracted while on the ground. This lowers the T.553, making it easier to move vehicles into the hold as they don't need to climb a ramp.

One aspect of the T.553 that made the type well suited to tactical operations was the type's short airfield performance; including the ability to perform steep descents of up to 20 degrees and perform landings on airstrips as short as 400 meters. In the airlift role, a later production T.553 could carry up to 8.5 tons across a distance of 5,000 kilometres, and take off from airstrips as short as 700 meters. Dependent upon aircraft configuration, a single aircraft could airdrop as many as 88 paratroopers or transport up to 93 equipped troops.

Advantages of the twin-engine configuration over four include reduced unit and production cost, lower weight and fuel consumption, simplified design and reliability. Each engine is equipped with an auxiliary generator system, providing the aircraft with both electricity and hydraulic pressure. An auxiliary power unit is used to power the aircraft while on the ground, and for rare use in mid-air emergencies.

An updated second generation of the T.553 was produced during the late 1980s and early 1990s. Amongst changes made, the new variant was equipped with additional fuel tankage, aerial refueling probes and enhanced avionics. While there were considerable changes to instrumentation, including the navigational and autopilot systems, the second generation T.553 retained the original operating characteristics to simplify crew transfers between types.

The T.553 proved to be a versatile aircraft, leading to a long operational service life. Between its introduction and 1999, approximately 2000 modifications and upgrades were incorporated upon the type, split 60/40 between the structure and equipment respectively. Many changes were made over time in regards to the aircraft's avionics, incorporating new features such as GPS and laser inertial navigation systems, modern autopilot and crew management systems.

Poja
The Pojački Air Force first acquired the T.553 Konge in 1964 through the Balashova Aircraft Company. Designated as the Ba-2 Konge, the Konge became the primary medium transport for the PAF. Eight variants of the original T.553 Konge were fielded between 1964 and 1978 and would continue to remain in service into the 1990s, replaced with upgraded aircraft beginning in 1988. The Konge continues to remain in service today with six variants in service with the Pojački National Air Force and the Pojački Territorial Air Force. Poja has purchased a total of 346 aircraft.

Chernarussian Conflict
In Pojački service, the Ba-2 Konge saw considerable use during the 6-year Chernarussian Conflict. The Ba-2 Konge-A saw action at the onset of the conflict when several aircraft were used to drop paratroopers behind enemy lines during the invasion. Thereafter, Ba-2 Konge-A aircraft were used to fly supplies into Chernarus to help keep troops resupplied. While initially, supplies were brought in via ground convoy, Chernarussian insurgents became particularly adept at ambushing those convoys, seizing t or destroying the supplies. As a result, this necessitated larger and larger convoys due to the added security elements, which ultimately prevented the convoys from reaching certain areas. Those areas were often resupplied via from the Konge. Later in the conflict, the Ba-2N Konge-E aircraft, which had more powerful engines, conducted drops to beleaguered  in the midst of insurgent attacks. One such firebase in 1973 survived being overrun solely by LAPES drops due to insurgents cutting off the roads to and from the base with ambush attacks.

During the war, Balashova modified several aircraft with and jamming equipment. Designated as the Ba-2SK Konge-D, these aircraft were used to locate insurgent bases through RDF but also to assist jamming their communications during offensive operations. The Ba-2SK's were highly capable and utilized with great success against the insurgency, especially during the last few years of the war.

The last modification to the Ba-2 Konge during the war came in 1972. Four aircraft were modified to be aerial gunships and equipped with a pair of autocannons and an  anti-aircraft gun. Designated as the Ba-2U Konge-F, these aerial gunships were used to assist troops conducting patrols or to assist firebases under insurgent attack. They were extremely reliable and pivotal in keeping troops alive and successful against insurgent attacks. In all, the PAF lost 17 aircraft during the war to all causes.

Modern Day
Following the end of the Chernarussian Conflict and the split of the PAF into the PNAF and the PTAF, 12 Ba-2 Konge-A aircraft were transferred into service with the PTAF while the Pojački military sought to replenish the aircraft it had lost in the conflict with an additional purchase from Hansen Flyfabrikk. The PNAF would go on to further develop its ELINT variants as well as make the gunship a permanent platform.

In the mid-80s, the PNAF approached Hansen Flyfabrikk with a request for a modernized variant. In what would eventually become the Ba-2M, the PNAF requested a modernized cockpit with, the powerful engines of the Ba-2N, and and buddy tanking capabilities. The new production run would see the older variants retired and sent to the scrapyards for recycling and the newer Ba-2M variants replace them. Modifications were made to the gunship variants first in 1992 and then again in 2006.

Buddy tanking capabilities was added via a palletized refueling system that would allow Ba-2M aircraft to refuel other aircraft via a system. The palletized aerial refueling package has an offload capacity of 13500 L or 10855 kg of fuel. A flexible host is trailed behind the aircraft at a distance of 30 m out of the of the aircraft. Any fighter or helicopter, provided it is equipped with a refueling probe, can refuel from the Konge with this package.

In 1995, a water bomber variant was procured to assist with fighting forest fires. The water bomber has a capacity of 12000 L of water or that can be deployed with the rear ramp of the aircraft in the closed and locked position. The system does not require pressurization during loading and allows the water or retardant to be sprayed out of two nozzles flanking the rear fuselage of the aircraft. The low stall speed of the Konge is a major assistance in dropping water or retardant accurately onto.

During Operation Zaporizhian Fire in 1997, the Ba-2 saw some limited use. Ba-2MU Konge-J gunships equipped with two cannons in place of the GSh-23Ls along with the 57-millimeter AZP S-60 provided fire support for Pojački troops. Ba-2MO Konge-L aircraft, equipped with ELINT and ECM equipment helped provide electronic warfare support, Ba-2MKO Konge-M aircraft assisted by acting as a radio relay, and Ba-2MSK Konge-N aircraft provided airborne communications jamming and psyops support while also acting as a radio relay.

Following the end of the conflict, several aircraft were modified specially to provide dedicated medical evacuation capabilities. These entered service in 2000 and in 2006, the Ba-2MUD Konge-R gunship was debuted featuring the same armament as the Ba-2MU Konge-J but the addition of four external pylons for precision-guided ordnance and a 120-millimeter mortar for additional firepower. As of 2021, the Ba-4 Konge-A has been retired entirely by the PTAF and they fly the Ba-4M Konge-K exclusively. The oldest variants in service are the Ba-2S Konge-B trainers in use with the PNAF.
