China’s J-20 stealth fighter jet is versatile, but it’s not perfect

By MICHAEL BRADY APRIL 9, 2017 11:31 AM (UTC+8)

Reports say China put its stealth fighter — the J-20 — into service last month. The aircraft, built by the Chengdu Aerospace Corporation, is a twin-engine multi-role fighter that can reach speeds of 2,100 kilometers per hour. It’s believed the J-20 will have two primary missions. First, it could be deployed as a long range air-to-air fighter capable of engaging aircraft such as tankers and intelligence reconnaissance planes used by the United States. Secondly, the J-20 could be used to bypass air-defense systems and serve as a strike fighter to attack ships or destroy land-based targets such as communication facilities.

The J-20 has some notable flaws. Most experts agree the aircraft possesses excellent low-observable (LO) stealth characteristics from the front angle. However, the rest of the fighter’s design suggests the aircraft would be identified by radar systems from side or rear angles. This would likely limit China’s potential role as a deep-strike fighter.

The J-20 gives the People’s Liberation Army Air Force the capability to engage targets at distances up to 200 kilometers using the PL-15 air-to-air missile. It’s unclear if the PL-15 is fully deployed now, but it’s predecessor, the PL-12, can reach targets up to 100 kilometers away. That capability gives it a significant military advantage against its lesser rivals in the South China Sea.

A military conflict in the South China Sea between China and other claimants such as Vietnam, Taiwan, Brunei, the Philippines or Malaysia, would likely result in a decisive victory for China unless, of course, the United States intervened on their behalf. Most of these countries do not have the capability to defend themselves since their naval and air forces are technologically inferior. In the case of Taiwan, it’s susceptibility to massive missile strikes from southern China make it nearly defenseless despite a strong military supported by US technology.

The aircraft would also be a “force multiplier” for any attack on Taiwan. China continues to assert its authority over Taiwan and any moves by the country to declare independence from Beijing would likely be met with a swift military response.

Many experts suggest that China would likely begin any large-scale military campaign against Taiwan by firing hundreds of cruise and ballistic missiles located in southern China. Rather than annihilating Taiwan with missile strikes and causing extraordinary loss of life, the J-20 could now be used to conduct a surgical strike against numerous potential targets. These include television stations, radar facilities, and command-and-control facilities. Doing so would send a clear message to Taiwan: remain a part of China or risk further military attacks.

China’s new stealth aircraft will allow it to enjoy military superiority over its rivals in the region. The J-20 will also require the US to reassess its military tactics to ensure “soft targets” such as tankers and intelligence aircraft survive any military engagements between the two countries. China will not enjoy military superiority over the United States but its latest stealth fighter moves it closer to regional hegemony.

La Fayette Class Frigate

The French Navy’s La Fayette Class multipurpose stealth frigates were developed by DCN International (now DCNS) and built at the DCN Lorient Naval Dockyard. The French Navy awarded DCN the contracts to construct the La Fayette (F710), Surcoef (F711) and Courbet (F712) frigates in 1988, and Aconit (F713) and Guepratte (F714) in 1992.

Missiles

(F-710) La Fayette

The ship’s surface-to-surface missile is the Exocet MM40 from MBDA (formerly EADS Aerospatiale). Two four-cell launchers are installed in a midship position between the two masts. The anti-ship missile has a range of 70km and approaches the target in sea skimming mode at high subsonic speed, approximately 0.95 Mach. The 165kg shaped charge warhead has time delayed impact proximity fuses.

(F714) Guepratte – Image: wikimedia.org

The French Navy has awarded MBDA a contract for the Exocet MM40 Block 3 missile to be deployed on vessels from 2006. The Block 3 missile will have a new turbojet propulsion system which will give a range extended to 180km.

Exocet MM40 Block 3

exocet-mm40-block-3

The MM40 Block 3 missile, complete with a Microturbo TRI 40 turbojet engine, began development 2004 and was first tested from a ship in 2010. Improvements to the MM40 Block 3 include internal navigation and GPS upgrades. These updates, combined with a frequency modulated continuous wave radar altimeter, allows for control of the missile’s altitude over various types of terrain. This missile is armed with a 160 kg high explosive/semi-armour piercing warhead and an active radar terminal seeker 9 Additional upgrades include increased evasive capabilities such as the ability to make a 180 degree turn post-launch, allowing the MM40 to evade defense missile systems. These upgraded missiles will be both ship- and ground-launched and will be deployed first onto Forbin (Horizon)-class destroyers and then to La Fayette-class frigates.

The 20 mm F2 is a mounted monotube gun, with two 150-cartridge boxes on each side of the piece. An electrical control system allows for a choice of three modes of fire: single shot, eight-shot burst, or free fire. There is an electrical trigger in the right hand of the gunner. A manual selector allows the gunner to change the box feeding the weapon during the firing, making mixed firing available. After each shot, the empty cartridge is ejected from beneath the weapon.

The gun is manoeuvred by the body of the gunner, who is attached to the weapon. Firing is guided through the same optical visor as used with the Bofors 40 mm gun and the Oerlikon 20 mm cannon.

SA 321G Super Frelon

To meet a French armed services requirement for a medium transport helicopter, Sud-Aviation flew the prototype SE.3200 Frelon (hornet) on 10 June 1959. Powered by three Turmo IIIB turboshafts, the SE.3200 had large external fuel tanks that left the interior clear for a maximum of 28 troops, and a swing-tail fuselage to simplify cargo loading. However, development was terminated in favor of a larger and more capable helicopter designed in conjunction with Sikorsky and Fiat. What was to become Western Europe’s largest production helicopter emerged with a rotor system of Sikorsky design, and with a watertight hull suitable for amphibious operation. Two military prototypes of the Super Frelon were built, the SA 3210-01 troop transport, and the SA 3210-02 maritime version for the Aeronavale on 28 May 1963.

   Four pre-production aircraft were built under the new designation SA 321 Super Frelon. These were followed in October 1965 by production SA 321G anti-submarine warfare helicopters for the Aeronavale. Apart from ship-based ASW missions, the SA 321G also carried out sanitisation patrols in support of Redoutable class ballistic missile submarines. Some were modified with nose-mounted targeting radar for Exocet anti-ship missiles. Five SA 321GA freighters, originally used in support of the Pacific nuclear test centre, were transferred to assault support duties. In 2003, the surviving Aeronavale Super Frelons were assigned to transport duties including commando transport, VertRep and search and rescue.

   Six radar-equipped SA 321GM helicopters were delivered to Libya in 1980-81. The SA 321G was also modified for air force and army service. Designated SA 321H, a total of 16 was delivered from 1977 to the Iraqi Air Force with radar and Exocet missiles. These aircraft were used in the Iran-Iraq conflict and the 1991 Gulf War, in which at least one example was destroyed.

Two Sagem Défense Sécurité (formerly EADS Defence & Electronics) Dagaie chaff and flare launching systems are installed on the gun deck aft of the bridge.

Dagaie chaff and flare launching systems

DAGAIE countermeasures system

The DAGAIE launcher comprises 6 or 10 munition containers, each of which is loaded with either IR or chaff rockets.
The firing sequence runs automatically and is triggered on a missile alarm from a variety of sources, such as radar, ESM systems, or optical sights, thus providing a very short reaction time. The firing direction is optimised in accordance with the threat bearing, wind-speed and direction, ship heading and speed data.
The launching of radar and IR decoys is so arranged that advanced mixed-guidance missile systems cannot discriminate between them and thus collocation of both decoys is achieved. The installation is a double mounting and comprises: (a) two trainable mountings carrying 10 replaceable containers (suitcases), each of which is loaded with either IR or I/J-band chaff projectiles.
A wide range of ammunition by Etienne Lacroix Défense provides seduction, distraction and
seduction/dissimulation modes. The electromagnetic decoys are normally based upon aluminised glass fibre chaff with rapid bloom time and they cover the I and J frequency bands. The infra-red decoys cover both the 3-5 and the 8-14 µm bands.
