The HAL Ajeet ( Sanskrit : अजीत ; IAST : Ajīt, lit. Undefeatable or Unconquerable ) was a jet-powered fighter aircraft developed and manufactured by Indian aerospace manufacturer Hindustan Aeronautics Limited (HAL). It was operated by the Indian Air Force (IAF) between 1977 and 1991.
97-591: The Ajeet is a derivative of the British Folland Gnat light fighter aircraft. The Gnat, which had been procured in large numbers for the IAF and produced under license by HAL, had acquitted itself favourably during its Indian service, including in active combat roles during multiple conflicts with Pakistan, including the Indo-Pakistani War of 1965 and the Indo-Pakistani War of 1971 . As such,
194-429: A company is brought to an end. The assets and property of the business are redistributed. When a firm has been liquidated, it is sometimes referred to as wound-up or dissolved , although dissolution technically refers to the last stage of liquidation. The process of liquidation also arises when customs , an authority or agency in a country responsible for collecting and safeguarding customs duties , determines
291-582: A shareholders' liquidation or members' liquidation , although some voluntary liquidations are controlled by the creditors). The term "liquidation" is also sometimes used informally to describe a company seeking to divest of some of its assets. For instance, a retail chain may wish to close some of its stores. For efficiency's sake, it will often sell these at a discount to a company specializing in real estate liquidation instead of becoming involved in an area it may lack sufficient expertise in to operate with maximum profitability. A company may also operate in

The parties which are entitled by law to petition for the compulsory liquidation of a company vary from jurisdiction to jurisdiction, but generally, a petition may be lodged with the court for the compulsory liquidation of a company by: The grounds upon which an entity can apply to
485-535: A Gnat at Lake Luonetjärvi . Gnat F.1 proved initially problematic in the harsh Finnish conditions. Finland was the first operational user of Gnat F.1, and the plane still had many issues yet to be resolved. All Gnats were grounded for half a year on 26 August 1958 after the destruction of GN-102 due to a technical design error in its hydraulic system, and the aircraft soon became the subject of severe criticism. Three other aircraft were also destroyed in other accidents, with two pilots ejecting and one being killed. Once
582-509: A capable lightweight fighter aircraft. Work to develop the Gnat went ahead, irrespective of any external orders or financing; there was no funding provided to support the type's early development from any British government department, such as the Ministry of Supply . Petter believed that a compact and simplified fighter would offer the advantages of low purchase and operational costs, and that
679-703: A common strike/attack light fighter with which to equip the air forces of the various NATO members. Although never used as a fighter by the Royal Air Force (RAF), the Gnat T.1 jet trainer variant was adopted and operated for some time. In the United Kingdom, the Gnat became well known due to its prominent use as the display aircraft of the RAF's Red Arrows aerobatic team. The Gnat F.1 was exported to Finland, Yugoslavia and India. The Indian Air Force became
776-466: A different powerplant from later-built prototypes and production aircraft, the demonstrator still used a nearly identical airframe along with similar onboard systems so that these could be proved in advance of the Gnat itself being built. This demonstrator was designated Fo-139 Midge . On 11 August 1954, the Midge performed its maiden flight , piloted by Folland's chief test pilot Edward Tennant . Despite

In some jurisdictions, the company may elect to simply be struck off the companies register as a cheaper alternative to a formal winding-up and dissolution. In such cases an application is made to the registrar of companies, who may strike off the company if there
970-548: A hundred Ajeets were ultimately procured and the whole programme was effectively terminated barely a decade after its initiation. The aircraft built had relatively short and uneventful careers, and were retired from IAF service during 1991. The Ajeet was never deployed in combat operations.

The Fo.147 was to have been capable of speeds in excess of Mach 2, with the speed limit set by the temperature of the structure as a result of kinetic heating. It had a maximum all-up weight of 18,500 lb (8,400 kg), comparing well with the Gnat 5's more restrictive 11,100 lb (5,000 kg) maximum. According to aviation author Derek Wood,

Accordingly, the aircraft was modified to conform with the requirements of Specification T.185D, which had called for an advanced two-seat trainer aircraft that could transition pilots between the current de Havilland Vampire T 11 and operational fighters, such as the supersonic English Electric Lightning . Folland proposed the two-seat Fo. 144 Gnat Trainer. The trainer model featured several changes, including
1358-415: A time to 50,000 ft (15,000 m) of 3 minutes, Folland estimated that a prototype could be flown as early as the end of 1962 and that the Gnat 5 could be readied for operational service within four or five years. In 1960, Maurice Brennan joined Folland as its chief engineer and director. Hawker Siddeley wanted to use his knowledge of variable-geometry wings in future designs. Under his direction,
1455-457: A variable geometry wing was applied to the basic Gnat 5 design to produce two different configurations – one tailless and one with a conventional tail – for a multipurpose fighter/strike/trainer, designated the Fo.147. The design used a unique mechanism to sweep the wings; this mechanism used a combination of tracks positioned on the fuselage sides, the centerline, and on the underside of the wings, and
1552-465: A voluntary winding-up of a company has begun, a compulsory liquidation order is still possible, but the petitioning contributory would need to satisfy the court that a voluntary liquidation would prejudice the contributors. The liquidator will normally have a duty to ascertain whether any misconduct has been conducted by those in control of the company which has caused prejudice to the general body of creditors.

In business terms this will mean liquidating a company as the only option and then resuming under a different name with the same customers, clients and suppliers. In some circumstances it may appear ideal for the directors; however, if they trade under a name which is the same or substantially

#17327804708122134-569: The Bangladesh Liberation War , Gnats flew anti-shipping operations, ground attack , bomber/transport escort and close air support operations. The IAF was impressed by the Gnat's performance in the two wars, but the aircraft had many technical problems including hydraulics, a temperamental pair of Aden 30 mm cannons which often failed in-flight, significant 'bent thrust' on take-off, leading to many aborted take-offs and an unreliable control system. To address these failings,
2231-664: The General Dynamics F-111K strike aircraft. The Folland Gnat was a purpose-built light fighter aircraft, suitable as both a trainer and a combat aircraft in ground-attack and day-fighter roles. The cockpit offered many features expected in standard fighter aircraft: full pressurisation , climate control , and an ejection seat . According to Folland, the Gnat offered advantages over conventional fighter aircraft in terms of cost, man-hours, handling, serviceability, and portability. Its tricycle landing gear let it operate from austere grass airstrips, thanks to
2328-510: The designation Gnat T Mk. 1 . The final Gnat T.1 for the RAF was delivered in May 1965. Folland sought to develop more capable versions of the Gnat; one of the more substantial of these proposals was tentatively designated as the Gnat Mk.5. This model was to be capable of supersonic speeds and was intended to be made available in both single-seat and twin-seat configurations, enabling its use in

As the design developed, differences between the Ajeet and the original model of the Gnat that had served as its starting point became considerable. During the development process, deliberate efforts were made to rectify the encountered shortcomings and troubles discovered within

For example, a party who had a valid contract for the purchase of land against the company may be able to obtain an order for specific performance , and compel the liquidator to transfer title to the land to them, upon tender of the purchase price. After
2619-605: The 1950s, the government of India had come to an agreement with the United Kingdom to procure a large number of Folland Gnat fighters, a light combat-capable jet-propelled aircraft, for the Indian Air Force (IAF). In addition to the acquisition of British-built Gnats, the type was also manufactured under a licensing arrangement in India by aviation company Hindustan Aeronautics Limited (HAL). During its production run, in excess of 200 aircraft were constructed by HAL for

The first production Gnat T.1s for the Royal Air Force were delivered in February 1962 to the Central Flying School at RAF Little Rissington . The major operator of the type was 4 Flying Training School at RAF Valley , the first aircraft being delivered in November 1962. In 1964 4 FTS formed the Yellowjacks aerobatic team with all-yellow painted Gnats. The team reformed in 1965 as part of

3104-452: The Gnat should be capable of being manufactured both cheaply and easily. The emergence of new lightweight turbojet engines, several of which were well advanced in their own development process, also enabled the envisioned light fighter concept to be realised. The Gnat was initially intended to be powered by a Bristol BE-22 Saturn turbojet engine, capable of generating 3,800 lbf (16.9 kN 1,724 kgp) of thrust. However, development of
3201-414: The IAF had a positive attitude towards the type, despite observing shortcomings in maintainability and some subsystems. Thus, during 1972, the service issued a requirement calling for the development of an upgraded and more capable variant of the Gnat, leading to the development of the Ajeet by HAL. In the design phase of the Ajeet, HAL redesigned several aspects of the aircraft while seeking to improve both
3298-623: The IAF issued a requirement for an improved "Gnat II" in 1972, at first specifying that the new version was to be optimised as an interceptor but then expanding the specification to include ground-attack. Over 175 of the Hindustan Aeronautics Limited -built licensed version, the Ajeet ("Unconquerable"), were produced in Bangalore . Several Gnats remain in use in private hands.

During its service life with the IAF, the Gnat proved to be relatively successful when deployed for active combat missions. The type was used in both the Indo-Pakistani War of 1965 and the follow-up Indo-Pakistani War of 1971 against neighbouring Pakistan. Operationally, it

Their work was greatly aided by an earlier decision by India to, upon the liquidation of Folland Aircraft during the 1960s, acquire many former assets of the company. The residual rights for the type had been transferred to the IAF while other items, such as
3880-399: The aircraft were heavily redesigned from the Gnat, such as the much enhanced hydraulic systems, the improved landing gear arrangement, and refined control systems, to produce superior performance, compared to their original counterparts. The control surfaces were enhanced via the adoption of a all-moving tail plane configuration, which was unique to the Ajeet. It was also decided to outfit

7469-493: The rising cost and size of typical combat aircraft, it was procured as a trainer aircraft for the Royal Air Force (RAF) as well as by export customers, who used the Gnat in both combat and training capacities. Designed by W. E. W. Petter , the Gnat has its origins in the preceding private venture Folland Midge . The issuing of Operational Requirement OR.303 by the British Air Ministry served to motivate
7566-466: The service had allegedly become increasingly opposed to the use of single-engine aircraft while a preference for fighters capable of supersonic speeds had also grown, as such, the Ajeet contrasted poorly with these new priorities. However, also according to Smith, the Ajeet benefitted both from the positive combat reputation garnered by the Gnat, as well as for its relatively low radar cross-section (RCS). Having fallen out of political favour, fewer than
7663-436: The subsequent aircraft. It had failed to interest the RAF as a combat aircraft at that time, but officers did issue encouragement of the development of a similar aircraft for training purposes. The larger Gnat, which was being developed in parallel with the Midge, was an improved version of the original fighter design; it was differentiated by larger air intakes to suit the Orpheus engine, a slightly larger wing, and provision for
7760-471: The time, such as the Hawker Hunter and the Gloster Javelin interceptors , were viewed as questionable. Petter examined the prospects for producing a more affordable but capable "light fighter", including a survey of available modern engines to power the type. Having identified suitable powerplant arrangements along with methods of making multiple key design aspects, such as the manufacturing of
7857-415: The total loss of individual Gnats and the deaths of several pilots. Accordingly, while the Gnat had been determined to be effective as a combat aircraft, it was also viewed that there was room for improvement on the design of its subsystems. During 1972, the IAF therefore issued a formal requirement, calling for the development and production of an improved model of the Gnat. Although the original revision of
7954-402: The trainer and interceptor role. The Gnat 5 was to be powered by either a pair of Rolls-Royce RB153R engines or two Viper 20 engines; in the interceptor role, it would be also equipped with a Ferranti AI.23 Airpass radar and armed with a pair of de Havilland Firestreak air-to-air missiles . Featuring an estimated maximum speed around Mach 2 (2,500 km/h; 1,500 mph) and
8051-528: The two wars were against Sabres despite the Canadair Sabre Mk 6 being widely regarded as the best dogfighter of its era. Tactics called for Gnats taking on the Sabres in the vertical arena, where the Sabres were at a disadvantage. As the Gnat was lightweight and compact in shape, it was hard to see, especially at the low levels where most dogfights took place. Apart from air defence operations, in
8148-417: The type's development; the Gnat was later submitted to meet this requirement. Its design allowed for its construction and maintenance tasks to be carried out without specialised tools, making it suitable for use in countries that had not yet become highly industrialised . The Gnat has been viewed as a major motivating factor towards the issuing of the NATO NBMR-1 requirement, which sought to make available
8245-515: The undercarriage; almost all new pilots would find it difficult to control the anticipated pitch up. With sufficient experience, pilots would exploit the nimble mini-sized aircraft to its limits. The Gnat is credited by many independent and Indian sources as having shot down seven Pakistani North American F-86 Sabres in the 1965 war . During the initial phase of the 1965 war, an IAF Gnat, piloted by Squadron Leader Brij Pal Singh Sikand, landed at an abandoned Pakistani airstrip at Pasrur and
8342-462: The wing. This had several effects on the overall design, including the substantial expansion of its internal fuel capacity and the freeing up of several underwing hardpoints that had been previously occupied by external fuel tanks, allowing for their use in the carriage of other equipment and armaments. Furthermore, the carriage of even-greater payloads was also enabled via the installation of an additional pair of underwing hardpoints. Certain aspects of
8439-400: Was actuated by hydraulically -driven ball screws positioned at the inner ends of the wings. The wings could be swept from 20 degrees to 70 degrees; at the 70-degree position, longitudinal control was maintained by wing tip-mounted elevons , and at the 20-degree position by a retractable canard arrangement. Auto- stabilisation was also to be used. By providing trimming with the canard,
8536-475: Was an extremely difficult aircraft to handle in the early stages of training. Unlike the RAF, the IAF did not buy a trainer version. Inductees were brought in from Hunter aircraft squadrons, having gained experience on powered controls. They then flew dual checks on the Hunter trainer. The pilot would do a brief full throttle run on the runway before flying solo. The Gnat had a tendency to pitch up sharply on raising
8633-539: Was captured by the PAF. Two Lockheed F-104 Starfighters claimed to have forced the Gnat down. Sikand — who had a complete electrical failure on his Gnat while he got separated from the IAF flight to fight a Sabre — had to make an emergency landing at the PAF field at Pasrur. This Gnat is displayed as a war trophy in the Pakistan Air Force Museum, Karachi . After the ceasefire, one Pakistani Cessna O-1
8730-400: Was closely followed by a third. However, information on the Ajeet trainer programme was received with a lack of interest on the part of the Indian government. IAF Air Commodore Jasjit Singh observed that there was little need for a trainer version of the Ajeet as the original Gnat had already been developed into a training aircraft and therefore could have been acquired already if the IAF had
8827-419: Was completed during 1991. The HAL Ajeet was a jet-propelled light fighter, primarily intended to function as a low-level interceptor aircraft , while also being capable of ground-attack missions. Being a derivative of the earlier Gnat, the aircraft appeared to be visually similar to its predecessor; the presence of a pair of extra underwing hardpoints being amongst the only obvious distinguishing features from
8924-537: Was in the United Kingdom on 11 January 1958, it was delivered to India in the hold of a C-119 , and accepted by the Air Force on 30 January 1958. The first Gnat squadron was the No. 23 (Cheetah) , which converted from Vampire FB.52 on 18 March 1960 using six Folland-built Gnats. The first aircraft built from Indian-built parts first flew in May 1962. The last Indian-built Gnat F.1 was delivered on 31 January 1974. The Gnat
9021-528: Was issued. On 31 August 1959, the prototype Gnat Trainer conducted its maiden flight from Chilbolton airfield , Hampshire . The Ministry did not at first place a production order as they were concerned about the size and ability of the company to take on a large order. Following the take over of Folland by Hawker Siddeley Aviation (becoming the Hamble division), further orders for 30, 20 and 41 trainers were placed between February 1960 and March 1962, receiving
9118-475: Was not evaluated in the competition, which was won by the Fiat G.91 . However, the Gnat was evaluated in 1958 by the RAF as a replacement for the de Havilland Venom , as well as other light aircraft such as the BAC Jet Provost . The Hawker Hunter was selected as the eventual winner of the fly-off competition. Although RAF interest in the possibilities for using the Gnat as a fighter had waned, Folland identified
9215-515: Was shot down on 16 December 1965 by a Gnat. The Gnats were used again by India in the Indo-Pakistani War of 1971 . The most notable action was the Battle of Boyra where the first dogfights over East Pakistan ( Bangladesh ) took place. IAF Gnats shot down two PAF Canadair Sabres and badly damaged one. Another notable dogfight involving a Gnat was over Srinagar airfield where a lone Indian pilot held out against six Sabres, shooting two Sabres in
9312-537: Was soon found to be a problematic aircraft in service and required a lot of ground maintenance. In early 1957 a licence agreement was reached to allow Valmet to build the Gnat at Tampere in Finland, although, in the end, none were built. On 31 July 1958, Finnish Air Force Major Lauri Pekuri , a fighter ace of the Second World War , became the first Finnish pilot to break the sound barrier while flying
9409-483: Was used to conduct both low-level air superiority missions and to perform short range ground attack runs. Due to its effectiveness against Pakistani fighters, such the North American F-86 Sabre , the type was given the moniker of Sabre Slayer . The Gnat was ultimately operated by the IAF for several decades up until its retirement during the 1980s. According to aviation author Pushpindar Chopra,
