Basic information about JF-17 Thunder aircraft program.

Basic information about JF-17 Thunder aircraft program.

Collaboratively produced by the Aviation Industry Corporation of China (AVIC) and Pakistan Aeronautical Complex (PAC), the JF-17 Thunder lightweight multi-role fighter is the emerging mainstay fighter platform of the Pakistan Air Force (PAF). Borne from the PAF’s need for an adept and affordable backbone fighter unencumbered by external, particularly Western, supplier costs and pressures, the JF-17 is also Pakistan’s gateway to aircraft manufacturing, custom integration and design and development work.

In 1995, PAC signed a memorandum-of-understanding (MoU) with the AVIC subsidiary Chengdu Aircraft Industry Group (CAIG) to co-develop and co-produce the JF-17, then known as the FC-1 and Super-7. The first Super-7/FC-1 prototype (renamed to JF-17) rolled-out from CAIG’s facilities in May 2003. In August 2003, the JF-17 prototype (PT-1) had conducted its maiden test flight in China. Development of the JF-17 airframe continued, with PT-4 incorporating noticeable changes, most notably the inclusion of diverterless supersonic inlet (DSI) and leading-edge root extensions (LERX).

For the final design, the PAF opted to use the Klimov RD-93 turbofan engine from Russia. The RD-93 is an afterburning turbofan engine with digital electronic engine control (DEEC). Its thrust (with afterburner) is 85.3 kN (8,700 kgf). The RD-93 is a variant of the Klimov RD-33, which powers the Mikoyan MiG-29. The JF-17 will be using the RD-93 for the foreseeable future, but PAC did not dismiss an engine change for the program. The Klimov RD-33MK and Guizhou WS-13 were listed as potential options.

In the cockpit, the JF-17’s human-machine interface (HMI) comprises of three multi-function displays (MFD), hands-on-throttle-and-stick (HOTAS) interface and head-up display (HUD). The JF-17 Block-I had used a hybrid flight control system: bank and yaw were managed mechanically and pitch electronically.

Under the co-production workshare agreement with AVIC, PAC would manufacture 58% of the airframe’s subassemblies, including its wings, horizontal stabilizer and vertical tail. The remaining 42% – including the fuselage – would be sourced from CAIG. However, final assembly would take place in PAC, which – via its Aircraft Manufacturing Factory (AMF) – has the capacity to rollout 25 JF-17s per year. In 2005, PAC began manufacturing certain components. By 2009, it had ramped up to manufacturing its share of the airframe.

The JF-17 entered PAF service in 2010 by replacing the PAF No. 26 squadron’s Nanchang A-5 Fantan attack aircraft. In 2011, the second (and final) A-5 squadron, No. 16, also switched over to the JF-17. The No. 16 and No. 26 operate the JF-17 Block-I, which was introduced to primarily deploy beyond-visual-range air-to-air missiles (BVRAAM), so as to bolster the PAF’s air defence capabilities.

The JF-17 Block-I was armed with the SD-10 BVRAAM, which was guided by the Nanjing Research Institute of Electronics Technology (NRIET) KLJ-7 multi-mode X-band pulse-Doppler radar. The NRIET KLJ-7 is capable of displaying 64 search targets in the Range-While-Search-mode and tracking eight targets under track-while-scanning (TWS) mode. It can simultaneously engage two targets with radar-guided air-to-air missiles, such as the SD-10 BVRAAM. The Block-I and Block-II are also armed with the PL-5EII within-visual-range air-to-air missile (WVRAAM).

In 2013, PAC and AVIC had begun manufacturing the improved JF-17 Block-II. The JF-17 Block-II introduced in-flight refueling capabilities through a removable hose-and-drogue probe and increased oxygen supply for longer-endurance flights. The JF-17 Block-II achieved full operational capability (FOC) in 2015. Since then, the PAF’s No. 2 and No. 14 squadrons had swapped their Chengdu F-7Ps for JF-17 Block-II fighters. As of 2017, the PAF has also certified the deployment of precision-guided and stand-off range munitions from the JF-17, specifically theRange Extension Kit (REK) and C-802 anti-ship missile. PAC will also integrate the ASELPOD electro-optical targeting pod from Turkey’s Aselsan, which will enable the JF-17 to guide munitions against fixed and moving targets as well as undertake reconnaissance roles.

By September 2017, PAC rolled-out 90 JF-17 Block-I and Block-II fighters. These have been deployed with four frontline squadrons and a fifth unit at the PAF’s Combat Commanders School (CCS). The PAF had originally intended to acquire 100 JF-17 Block-I and Block-II fighters to help supplant 190 legacy F-7P and Mirage III/5 fighters. The PAF envisages equipping the JF-17 with the same kinds of air-to-surface and air-to-air munitions found on contemporary platforms, be it BVRAAM, WVRAAM, laser-guided bombs (LGB), precision-guided bombs (PGB), anti-ship missiles and, eventually, air-launched cruise missiles and various other stand-off range munitions (e.g. glide bombs and anti-radiation missiles).

Having realized the JF-17’s preliminary goal of being an affordable and adept backbone fighter, the PAF is now steering the JF-17 to become its qualitative driver. Historically, imported fighters from the West were viewed as means to introduce new-generation systems and capabilities to the PAF fleet, but with the rising cost of importing such arms, the PAF has staked that essential role to the forthcoming JF-17 Block-III.

The PAF expects to see the JF-17 Block-III enter production in 2019 or 2020. The JF-17 Block-III will utilize an active electronically-scanned array (AESA) radar , which will imbue the JF-17 with enhanced defensibility against electronic warfare (EW) jamming. This will join an integrated electronic countermeasures (ECM) and EW suite along with a helmet-mounted display and sight (HMD/S) system. The JF-17 will also be configured with a high off-boresight (HOBS) AAM (see Quwa’s background briefs on HOBS AAM and HMD/S for context). The JF-17 Block-III will also eschew the hybrid flight control system for a three-axis fly-by-wire (FBW) flight control system.

Bridging the JF-17 Block-II and the JF-17 Block-III is the two-seat JF-17B. The JF-17B made its maiden test flight in April 2017. The two-seat variant incorporates several design changes to the JF-17 Block-I/II, among them a swept-back vertical stabilizer. The first JF-17B was joined PAF in December 2017.

How China and Russia can defeat USA in air to air war?

How China and Russia can defeat USA in air to air war?

There is not much official information available about PLAAF's J-20, the aircraft appears to have been optimized to high-speeds, long-range, stealth and a heavy internal payload. With a combination of reduced radar cross-section and high supersonic speed.
Armed with internally carried PL-15 missiles. It is possible that the J-20 could be used to threaten U.S. Air Force tankers and ISR assets in the Pacific theatre.
Chinese derivatives of the Su-27 Flanker can become threat for U.S. tankers, maritime patrol and command and control aircrafts by using long-range air-to-air missiles.

A new generation of Russian and Chinese-built long-range air-to-air missiles could threaten the critical nodes that enable U.S. air operations. Those nodes include the AWACS, various intelligence, surveillance and reconnaissance (ISR) assets, aerial refueling tankers and electronic attack aircraft.

While often overlooked in favor of advanced anti-ship and surface-to-air missile systems when examining Russian and Chinese anti-access/area denial (A2/AD) capabilities, such long-range air intercept weapons,coupled with the right fighter, could cut the sinews that allow the United States to conduct sustained air operations in both the Asia-Pacific and the European theatres.
 Essentially, Russians and/or Chinese forces could pair long-range air-to-air missiles with aircraft like the Mikoyan MiG-31 Foxhound, Sukhoi T-50 PAK-FA and the Chengdu J-20 to attack American AWACS, JTARS and aerial refueling tankers like the Boeing KC-135 or forthcoming KC-46 Pegasus.
 Especially over the vast reaches of the Pacific where airfields are few and far away.

There are three long-range air-to-air missile programs that bear watching—the Russian Vympel R-37M RVV-BD, the Novator KS-172 (aka K-100) and the Chinese PL-21.

Russia’s new R-37M RVV-BD long-range air-to-air missile is already at the initial operational capability (IOC) stage onboard the Mikoyan MiG-31BM Foxhound. It will also eventually be integrated onboard the Sukhoi Su-35S Flanker-E and the T-50 PAK-FA stealth fighter . The RVV-BD—also called the AA-13 Arrow by NATO, is claimed to have successfully intercepted targets at ranges greater than 160 nautical miles .

“The improved R-37M missile is in serial production since 2014, and now, apparently, it is in an IOC stage in squadrons of MiG-31BM upgraded interceptors. This missile is also planned for use on the T-50 fighters.

The original R-37 was originally developed by the Soviet Union to attack high-value NATO air assets such as the E-3 Sentry AWACS, E-8 JSTARS and RC-135V/W Rivet Joint. The idea was to use a high-speed fighter such as the MiG-31 which can sustain speeds of Mach 2.35 over a radius of 390 nautical miles while carrying a significant air-to-air payload with the new missile to eliminate those NATO air assets.
 An aircraft like the MiG-31 or a stealthy supersonically cruising airframe such as the PAK-FA—is ideal for such a mission because they are difficult to intercept due to their sheer speed and altitude.

After the 1991 collapse of the Soviet Union, the Russian defense industry continued work on the R-37 project but progress came slowly. The 1990s was an especially difficult time for the Russian defense industry as funding slowed to a trickle. Indeed, the original Soviet-era R-37 was cancelled before being restarted as the current RVV-BD variant.

The R-37M is likely to utilize a combination of inertial guidance with course corrections from the launch aircraft and active radar guidance for the terminal phase. During combat operations, aircraft like the MiG-31 would make a high-speed dash towards its target and launch a numbers of R-37Ms.
The Foxhound would likely track the target with its powerful Zaslon-M phased array radar and feed data to the missile until the weapons’ own radar went active. It might also have a home-on-jam feature similar to the one found onboard the U.S.-made AIM-120D AMRAAM to counter airborne electronic attack aircraft such as the Boeing EA-18G Growler.

The Soviet Union was well aware that one of NATO and the United States Air Force’s primary advantages was their ability to run a coordinated air campaign using assets such as the AWACS.
The Soviet Union explored a variety of methods to counter aircraft such as the AWACS,including passive-homing long-range air-to-air weapons. E.g, K-100.
(the theme of air-to-air missiles with passive radar homing was popular in the Soviet Union in the 1980s)

Indeed, the problem is not just that the PL-15/21 would out-range the AMRAAM, when coupled with the J-20, the Chinese could attack the tankers and ISR aircraft that would be the key enablers during any air campaign over the Pacific.

In order to sustain F-22 operations over Taiwan from Guam, the U.S. Air Force would need to launch three to four tanker sorties per hour to deliver 2.6 million gallons of fuel. That’s a fact that has not likely escaped Beijing’s air to air attack, and these attacks can put America in great loss or a big defeat in Air to Air war.

Pakistan successfully training launch nuclear capable tactical Nasr Ballistic missile.

Pakistan successfully training launch nuclear capable tactical Nasr Ballistic missile.

(24-01-2019)


The Nasr is a solid fueled tactical ballistic missile system developed by National Development Complex (NDC) of Pakistan.

It can equipped with 400 kg conventional high explosive, cluster munition or plutonium or uranium tactical nuclear weapon.

It is a Multi-tube Ballistic missile and its launcher can launch multiple missiles in a time. Its first test was occurred in during 2011 and it entered service after further testing in 2013.

It is a small ballistic missile which carries a sub-kiloton tactical nuclear weapon out to a range of 70km.

 The system appears to have been developed as a "low-yield battlefield deterrent" targeted at "mechanized forces like armed brigades and divisions.

It is believed by analysts that the system is deployed to deter and respond to India's "Cold Start" doctrine.

It have high accuracy, shoot and scoot attributes" for "quick response.

Pakistan confirmed that these tactical nuclear weapons are intended to be used against Indian troops on Pakistani soil. According to analysts, if used just inside Pakistani territory, it would counter cold start doctrine and maximize ionizing radiation exposure while minimizing blast effects which would be more dangerous for the Indian army than for local people as the blast yield is much lower than strategic nuclear weapons.

The very first Blue on Blue incident in "Subcontinent" First friendly fire causality region of subcontinent.


The very first Blue on Blue incident in
 "Subcontinent"
First friendly fire causality region of subcontinent.

 Achievement is held by none other than indian airforce during the 1971 indo-Pak war.

During 1971 war, Pakistan air force operated Dassault Mirage IIIR for photo reconnaissance  missions. Mirages conducted regular photo reconnaissance missions in Ferozpur area to update ground commanders about indian reinforcement efforts aimed at vacating the incursion.

An important mission involved reconnaissance of crossing points over Gang Canal for a careful scrutiny of obstacles across the waterway that could possibly impede the movement of II Corps of indian army.

Two pilots who played a sterling role in the photo reconnaissance operations were Sqn Ldr Farooq Umar and Flt Lt Najib Akhtar. Of the 30 photo reconnaissance  sorties(besides 15 escorts)flown by No 5. Squadron "Falcon" before and during the war, 22 were considered successful.

In Shakargarh Sector,a few night reconnaissance missions were attempted with partial success.
In one such mission on the night of 11 December ,an IAF mig-2Fishbed tried to intercept a Mirage flown by Sqn Ldr Farooq umar.

But instead of getting a frag on enemy aircraft ,the Mig-21 ended up shooting down one of its own Mig-21s flown by Flt Lt A B Dhavle, which was patrolling in vicinity.
 Four-odd Bomb Damage Assessment missions were also flown following the initial strikes on runways.

Defence comparison of Indian Kolkata class destroyer and Chinese Type 054A+ Frigate

Defence comparison of Indian Kolkata class destroyer and Chinese Type 054A+ Frigate


Defence is one of the most important parameters of any Naval ship. A ship quality is mostly based on it defence not its attack.
For defence against fighter jets Surface to air missiles are mounted on the ship and to protect against the incoming missiles Close in weapon system (CIWS) are mounted on it.

Here is a comparison of Indian front line ship Kolata class destroyer and Chinese Type 054A+ Frigate which Pakistan ordered (4 of them)

Remind you we are comparing a destroyer with a frigate so you would expect that in every case the destroyers must overcome the frigate by far margin but the result is something else. Not much difference. Either the modern Chinese frigate is close to destroyer or Indian Destroyer is less armed for a destroyer


∆.Displacement
Kolkata class destroyer: 7500 tons
Type 054A+ Frigate: 4100 tons

∆.Surface to air Missiles
Indian Kolkata class destroyer uses Israel made Barak 8 missiles. 4x8 cells (32) are mounted on the ship. Barak 8 has a max range of 90 km.

Chinese Type 054A+ is mounted with 1x32 cells HQ-16 missiles of Naval variant. HQ-16 (Naval variant) has a max range of 75 km.


Conclusion:
As a destroyer you expect Kolkata class to be equipped with more than 32 missiles with range more than 120-130 km. While Type 054A+ Frigate to be equipped with 35-40 km range with less than 32 missiles but it ant happening here.


Close in Weapon System (CIWS)
CIWS engaged upcoming antiship missiles

Kolkata class:
Kolkata class consists of 1x4 Soviet/Russian made 1ST generation AK-630 CIWS. Develop in the 1970. Russia now uses Kashtan (Chestnut) CIWS which is the best CIWS in the world. AK-630 1st Generation is still exported to other countries like India and it is also used by Russia to protect its smaller ships like corvettes. It can effectively detect upcoming missile traveling at a speed of mach 2.
Fire rate: 5000 rounds per minute
Range: 4 km
Develop: 1970

Type 054A+
Type 054A+ is mounted with Type 1130 Third generation CIWS which is one of the best CIWS that it is able to intercept incoming anti-ship missiles up to a speed of Mach 4 with a 96% success rate.
Fire rate: 11,000 rounds per minute
Range: 3 km
Develop: late 2000

Type 054 consists of 3 variants. The early Type 054 consists of same type of CIWS which is mounted on Kolkata class i.e. 4x 1ST generation AK-630 CIWS. Later in Type 054A Chinese made 2nd generation Type 730 CIWS were used. 2x type 730. These 2 can provide more safety than those old 1st generation 4 AK-630 CIWS. Later in Type 054A+ 3rd generation Type 1130 CIWS is used.


Not only 2 x type 1130 ciws are mounted on type 054A+ frigate 2 × Type 726-4 18-tube decoy rocket launchers are also mounted on it. decoy launching system provide 360° coverage, and will effectively counter advanced threats like small range gate Radio Frequency (RF) missiles, imaging Infra-Red (IR) seekers missiles, and advanced next generation torpedoes. Defense against multiple missiles and torpedoes requires fast response and utilization of advanced tactics supporting the latest in decoy technologies


Conclusion
Despite being a frigate Type054A+ CIWS are better than Kolkata class destroyer. Not in quality but also in QUANTITY.

World's most deadly short range MBRLs and its users?

World's most deadly short range MBRLs and its users?


TOS-1 is a 220mm heavy multi barrel rocket launcher was designed against heavy ground forces during 1987.

It have 500-6000m effective range and can fire whole 30 rockets in just 15s.

TOS-1s were first used in combat in Afghanistan's Panjshir valley by the Soviet Union during the Soviet–Afghan War.

Later, they were used during the Second Chechen War, prominently by the Russian Army during the Battle of Grozny in 1999.

TOS-1As were first used in combat in Iraq by the Iraqi Army in the recapture of Jurf Al Sakhar on October 24, 2014 from ISIL forces.
The Iraqi Army launched at least three TOS-1 rockets on 18 June 2017 during the first day of an offensive to recapture the Old City of Mosul, Iraq, from the Islamic State, targeting school buildings held by Islamic State forces and known to be devoid of civilians.

The OSCE reported in September 2015 that the TOS-1 was sighted in a rebel training area in eastern Ukraine.

The TOS-1 was used in Syria on October 10, 2015 by Syrian Army forces against rebel forces in Hama.

In 2016 it was used against rebel forces in the Latakia mountains.

It was used again by the Syrian Army in April 2017 in the area of Palmyra, and later that same month to destroy an ISIS camp.

 Used once more by the SAA against ISIS in Al-Safa region in November 2018.

Azerbaijan used the TOS-1A against the Nagorno-Karabakh Defense Army on April 4, 2016.

Still these systems are under service of more than four countries.
