JF-17 Saudi Export

Royal Saudi Air Force emblem.
Recent reports of Saudi interest into a JF-17 purchase appear to be wide of the mark. Though such a sale is certainly not impossible (and there is strong pressure on Pakistan to secure an export order), it is likely improbable. 


The Saudi air force is currently retiring or has already retired a large number of aircraft as part of its modernisation efforts. The F-5E/F and Tornado ADV fleet have been retired or have been relegated to the training role, and more F-15s and Typhoons ordered in their place as the well funded RSAF can afford such high tech aircraft. Though the JF-17 was designed to replace aircraft such the F-5, of which over a hundred at one time flew in Saudi service, the purchase of advanced western aircraft points to efforts by the Saudis to make a wholesale improvement in their airpower by phasing out lightweight fighters. Even in the training role further Hawk trainers as LIFT and light strike aircraft could easily fill in the second line fighter requirement if there was one. Coupled with upgrades being made to existing F-15S and Tornado IDS strike aircraft, the chances of there being a role for the JF-17 to fill are reduced.

The purchase of advanced western weaponry also buys the Saudis a degree of influence as its multi-billion dollar deals have been instrumental in ensuring the profitability of western arms firms during periods of uncertainty. As was seen with the ending of the British investigations surrounding the Anglo-Saudi Al-Yamamah arms deal in 2006, Saudi influence can be substantial.

A possible JF-17 sale however, could eventuate if negotiations for further Typhoon aircraft for example are not fruitful. With 72 Typhoons on order the negotiations for a further batch of 72 are ongoing. However, the Saudis could at least explore the option of a JF-17 purchase if only to pressure the British into accepting more favourable terms. Considering the strategic logic the Saudis operate by in which they effectively buy influence a possible purchase may also rest on how they view the growing power of China. China has made some progress in penetrating the Saudi market with its commercial goods and has even built a public transit system in Mecca. China was also the country the Saudis turned to when it decided to purchase ballistic missiles in the 1980s. The Chinese could therefore pick up a sale as a vendor of last resort, or as a country that the Saudis believe is now important enough to view as a potentially strong influence in the region. This could be linked to the Saudi view of needing to contain Iran. Therefore purchasing the Sino-Pakistani FC-1/JF-17 could be part of such thinking. However, this is purely speculation and a Saudi purchase is, for the best part, unlikely.

The reports may be yet another example of Pakistani officials feeding such speculation to the local media, which has then reported them as fact. Unnamed US journal that has been quoted in recent reports aside, the likelihood remains slim. This is especially when considering past examples of large scale arms sales to Saudi Arabia. When Saudi Arabia was reportedly interested in purchasing the HIT Saad APC there was considerable speculation a sale would also include the Al-Khalid MBT. Though a Saad sale was a reasonable enough belief, the Al-Khalid sale was unrealistic as the Saudis have the ability to purchase better armoured and armed tanks than the Al-Khalid even in that class of medium MBT.

A Saudi JF-17 purchase therefore is most likely unrealistic.

Whos Going To Shoot Down "Raptors"

The image in this post was taken from a U.S. Air Force F-15 Eagle from the 131st Fighter Squadron, 104th Fighter Wing, Barnes Air National Guard Base, Massachusetts, during a close range aerial combat exercise against a U.S. Air Force F-22 Raptor from the 154th Wing, Joint Base Pearl Harbor-Hickam, Hawaii.

You can clearly see the two planes maneuvering at very close range, pulling Gs, with the F-22 releasing flares counter measures against (simulated) heat seeking air-to-air missiles.

The dogfight took place off the coast of Penang, Malaysia, Jun. 16, 2014, during “Cope Taufan 2014″ a biennial LFE (large force employment) exercise taking place June 9 to 20 designed to improve U.S. and Malaysian combined readiness.

Both aircraft are currently deployed to Royal Malaysian Air Force P.U. Butterworth, Malaysia.

The exercise, that marks the F-22’s first deployment to Southeast Asia, featured also some interesting mixed formation between U.S. planes with Royal Malaysian Air Force MIG-29N Fulcrum, Su-30 and F-18 Hornet jets.

It’s not clear whether the F-22 has flown DACT (Dissimilar Air Combat Training) against Malaysian Migs or Sukhois; if this is the case, it would be interesting to know which ROE (Rules Of Engagement) were applied and the outcome of the confrontations between the Russian multirole planes and the U.S. most advanced fighters.

Durandals: The Formidable Penetrators of PAF

The Durandal is a anti-runway penetration bomb developed by the then Matra of France, which is now known as the MBDA,  designed to destroy airport and airfield runways.
The Durandal was adopted by the US in a slightly modified form (with a steeper impact angle and a higher 630 knot deployment speed) as the BLU-107/B in the 1980s, and carried by F-111 and F-15E strike aircraft.

This Durandal is in service with Argentina, Turkey, Pakistan and at least 13 other nations. There is some obscure information as to whether the Durandal is or ever has been in service with the French Armée de l'Air.

In the war it was used by the USAF in Desert Storm. 20th Wing (operating
F-111E's) flight commander Captain George Kelman said "there is nothing better at destroying a runway than a Durandal."
China has developed its own anti-runway bombs, the Type 200A, based on Durandals.
Durandals are Designed to be dropped from low altitudes, the bomb's fall is slowed by a parachute. 

  • The maximum release speed is 550 knots (1,020 km/h; 630 mph), and 
  • The minimum release altitude is 200 feet (61 m). 
When the bomb has reached a 40° angle due to the parachute's drag, it fires a rocket booster that accelerates it into the runway surface. 

It works in a way of "dual action":

  1. The 100-kilogram (220 lb) primary charge explodes after the penetration of the weapon into the concrete and drives the secondary charge even deeper.
  2. The 15-kilogram (33 lb) secondary charge then explodes after a one-second delay.  
Later production weapons have a programmable fuze that can delay the secondary detonation up to several hours. The weapon can penetrate up to 40 centimetres (16 in) of concrete, and creates a crater 2 metres (6 ft 7 in) deep and approximately 5 metres (16 ft) in diameter. In addition, concrete slabs around the crater are disturbed in an area approximately 15 metres (49 ft) in diameter. The disturbed slabs are displaced up to 50 centimetres (20 in) above the original surface, making repair more difficult than the simple crater from a conventional bomb

American Classic Multirole Fighter - McDonnell Douglas F-15E Strike Eagle/ F-15SE (Silent Eagle)_Part-II

























American Classic Multirole Fighter - McDonnell Douglas F-15E Strike Eagle/ F-15SE (Silent Eagle)_Part-I










Boeing F-15SE Silent Eagle, United States of America




F-15SE Silent Eagle is an upgraded version of the F-15 Strike Eagle aircraft, being developed by Boeing for international customers. The F-15SE features an innovative design which reduces its radar cross section. A prototype of the F-15SE Silent Eagle aircraft was first unveiled in March 2009. The F-15SE flight demonstrator aircraft, F-15E1, completed its maiden flight in July 2010.

F-15SE Silent Eagle design

"The F-15SE flight demonstrator aircraft, F-15E1, completed its maiden flight in July 2010."
F-15SE is 63.6ft (19.4m) long, 18.5ft (5.6m) high and has a wingspan of 42.8ft (13m). The basic design of the F-15SE is similar to that of the F-15 Strike Eagle aircraft with new components added. The new components include the conformal weapons bay (CWB) instead of the standard conformal fuel tanks.
The CWB significantly increases the internal carriage capacity of the aircraft and also reduces its radar signature. Two additional weapons stations have been included to enable the aircraft to carry an additional four air-to-air missiles.
The Silent Eagle also features twin vertical tails canted 15° outward. Canted tails provide rear lift to the aircraft and reduce ballast usage, while increasing the range by 75 to 100 nautical miles. Coatings will also be applied to various areas of the aircraft to minimise the radar signature.
The F-15SE has also been designed to function as a non-stealthy, multirole aircraft. The CWBs can be removed and the aircraft can be reconfigured to include conformal fuel tanks based on mission requirements.

F-15SE Silent Eagle development programme

Boeing commenced development of the F-15SE as an evolution to the F-15 family of aircraft. The company signed a Memorandum of Understanding with Korea Aerospace Industries in November 2010 for development of the F-15SE's CWB.
Boeing successfully completed the weapons launch from the left CWB of the F-15E1 flight demonstrator aircraft in November 2010. The F-15E1 launched an inert AIM-120 demonstrating the aircraft's ability to deploy a missile in flight.
"The F-15SE can carry air-to-air missiles, such as AIM-120 and AIM-9, and air-to-ground weapons."
Wind tunnel tests on the CWB of the Silent Eagle were completed in June 2012. A scale model of the aircraft was used to test aerodynamics of the CWB design.
Boeing has offered the aircraft for the F-X III competition launched by South Korea's Defense Acquisition and Procurement Agency to procure 60 new fighter aircraft for the Republic of Korea Air Force. The F-15SE is competing for the $7.3bn order with the Eurofighter Typhoon and Lockheed Martin's F-35.
The three companies submitted their formal bids in June 2012. South Korea was scheduled to decide the winner of the competition in October 2012 but the decision has now been postponed to mid-2013.
New orders from Saudi Arabia and Japan are also the driving forces behind the development of the next generation of F-15 aircraft. The development cost of F-15SE is estimated at $100m each. Boeing plans to offer the aircraft to five foreign customers with an estimated market for 190 orders. Flight testing of the F-15SE is expected to be carried out in 2013.

Aircraft engines, cockpit and avionics

The F-15SE will be fitted with two General Electric F110-GE-129 turbofan engines providing thrust of 29,000lbs or two Pratt & Whitney F 100-PW-229 engines providing thrust of 29,000lbs.
The F-15SE will feature next-generation Joint Helmet Mounted Cueing System produced by Vision Systems International, Elbit 11in x 19in Large Area Display (LAD) system on the front and rear cockpits, digital fly-by-wire flight control system, Link-16 Fighter Data Link and infrared search and track (IRST) system.
An advanced targeting pod provides the aircraft with target identification and autonomous tracking capabilities. A navigation pod will also be fitted to the aircraft providing it with all-weather and night-attack capabilities.
The aircraft will also feature advanced electronic equipment including BAE Systems digital electronic warfare system (DEWS) and active electronically scanned array (AESA) radar.

F-15SE weapons and performance

The F-15SE can carry air-to-air missiles, such as AIM-120 and AIM-9, and air-to-ground weapons including precision-guided weapons, JDAM and globules admire. The F-15SE can fly at a maximum speed of 2,655km/h. It can climb at the rate of 15,240m/min. The aircraft will have a range of 3,900km and a service ceiling of 18,200m. The empty weight of the aircraft will be 14,300kg and the maximum takeoff weight will be 36,741kg. The aircraft can carry a payload of 11,748kg.
