    Hongdu L-15 is a twin engine, modern jet trainer or light attack aircraft designed and manufactured by Hongdu Aviation Industry Group (HAIG) of China. It has been built as a rival to Guizhou JL-9/FTC-2000 Mountain Eagle. The L-15 will be used as a lead-in fighter trainer (LIFT) by the People's Liberation Army Air Force (PLAAF) and the People's Liberation Army Naval Air Force (PLANAF). About five prototypes have been built by HAIG.

    Hongdu L-15 trainer aircraft orders

    PLAAF ordered four Hongdu L-15 trainer aircraft in April 2006. Pakistan Air Force (PAF) is planning to procure Hongdu L-15 supersonic jet trainers from HAIG to replace its existing K-8 Karakorum jet trainer. The procurement will allow PAF to reduce its trainer aircraft from four to two.



    Hongdu L-15 design

    HAIG unveiled the L-15 aircraft design in September 2001 during the 9th Aviation exhibition in Beijing. The large leading edge extensions (LEX) design allows the aircraft to offer a maximum angle of attack of 30°. The aircraft can also be changed into light air-to-ground attack aircraft with minor modifications.

    The aircraft has been designed to train pilots of the Fourth-generation fighters encompassing Su-27, Su-30, J-10, and J-11. The enhanced design provides safety to the pilot while cutting down the training cost compared to its rivals.

    HAIG L-15 development

    The development of Hongdu L-15 began when Hongdu planned a modern trainer aircraft which would meet the requirements of PLAAF's new generation fighters. Russian based Yakovlev Design Bureau aided in the L-15 manufacturing as its design resembles that of the Yak-130 aircraft.

    "HAIG unveiled the L-15 aircraft design in September 2001 during the 9th Aviation exhibition in Beijing."

    The initial prototype was rolled out in September 2005 and took its maiden flight in March 2006. The second prototype completed its first flight in May 2008. The first and second prototypes are powered by two ZMKB-Progress (Lotarev) DV-2 engines. An improved version, the DV-2F, which boasts of afterburner capabilities, was fitted in the third model. Ukraine's Ivchenko-Progress AI-222K-25F turbofan engines with afterburner are incorporated in the later L-15 versions.

    The Hongdu L-15 was displayed at the Dubai Air show organised in November 2009 to promote its aircraft in the potential Middle East market. HAIG will receive export orders from Africa, the Middle East and South America.

    The first operational variant powered by Ivchenko-Progress AI-222K-25F turbofan engines was introduced in August 2010 upon completion of six months production.

    Hongdu L-15 cockpit

    The Hongdu L-15 features a full glass cockpit which can accommodate two crew members, either a student pilot and instructor, or an official pilot and weapons systems officer. A multi-colour head down display is fitted on both front and rear cockpit, while the head up display is installed at the cockpit front. Digital fly by wire (FBW), and hands-on throttle and stick (HOTAS) flight control systems are also installed in the aircraft.

    Armaments

    The Hongdu L-15 comprises six hard points of which four are located under the two wings and two under the wing-tips. It can accommodate 3,000kg of payload. The aircraft can carry short range air-to-air missiles, air-to-ground missiles, bombs and rocket pods.

    Ivchenko Progress AI-222K-25F Engines

    The aircraft is powered by two Ivchenko Progress AI-222K-25F afterburning turbofan engines. Each engine can generate 4,200kg of thrust afterburner.

    "The Hongdu L-15 can climb at the rate of 150m/s."

    The aircraft is also integrated with full authority digital engine control (FADEC), which decreases the work load of the pilot by executing autopilot operations.

    The length and width of the engine are 2.2m and 0.86m respectively.

    The height is 1.09m. The service life of the engine is 3000 flight hours, while the dry weight is 440kg.

    Performance

    The Hongdu L-15 can climb at the rate of 150m/s. Its maximum speed is 1,715km/h. The range and combat radius of the aircraft are 3,100km and 550km respectively. The service ceiling of the aircraft is 16,000m. Its maximum loitering time is two hours. The aircraft weighs around 4,960kg and its maximum take-off weight is 9,500kg.

    Don't know but whats interesting about L-15 is that it has twin engines. Does that mean PAF wants to train it's pilots for twin engined fighter jets such as J-11 or J-31 in near future ?

    I think for right now Pakistan Air Force will keep K-8 for fighter conversion but order a Squadron of L-15 for the Advanced supersonic conversion for future fighters like J-10B and J-11.

    It looks like something is cooking, as PAF is ramping up its Trainer profile quite aggressively. We still have the T-37 Tweetie birds that have been upgraded and have a life of another 10 years at the very least. At the same time PAF has ordered 75 more K-8's and now few L-15s ( although we don't know how many have been ordered but I am sure the number would be small for right now ).

    It certainly appears that the L-15 have been ordered to fill a special need ( niche ). In any event, it is an excellent development as the trainer is supersonic ( mach 1.6 ) and a twin engine trainer.

    Great news, looks like PAF wants twin engine fighter jets in the future but before that PAF wants to train their pilots before they purchase the twin engine big fighters.

    INSHAALLAH more good news to come.

    Hi, I will take the more cautious approach and believe it when they are delivered.

    Moreover, I highly doubt the K-8 is being retired. The PAF just upgraded the K-8s delivered in the early 90s to a full glass cockpit, for them to be standardized with the newer delivered ones. I think this website might be referring to the MiG-15 trainers in the PAF being phased out, if they have not been retired already. Moreover, this website is not updated on a daily basis, and has some old information.

    I agree with you in that I doubt PAF will retire its fleet of K-8 as it just ordered more of those. However, the news of L-15 is confirmed and it is not just one website reporting this but multiple sites are confirming purchase of L-15.

    I don't think we will purchase large quantities yet as it is meant to bridge the Gap between K-8 and our more advanced fighters. Additionally , this might be a shift in PAF doctrine of Single engine fighters to Twin Engine variants in future e.g. J-11 etc in addition to single engine J-10B.

    In November 2012, there was roumour that 12 L-15s were sold to unknown customer. The order would have to be delivered in 2013.

    Unknown Customer could be Pakistan!!!
