The Rockwell XFV-12 - an experimental supersonic fighter prototype

 The Rockwell XFV-12 was an experimental supersonic fighter prototype developed for the United States Navy in the 1970s. It was designed to have vertical takeoff and landing (VTOL) capability and a speed of Mach 2.

Design and Technology

This aircraft had a unique design to support operations from small aircraft carriers called Sea Control Ships.

Thrust Augmented Wing (TAW): Utilized a thrust-augmenting wing concept, where holes in the wing, similar to "Venetian blinds," would open to direct engine jets downward to generate vertical lift.

Wing Configuration: With a rear main wing and canards (winglets) at the front, measuring nearly 50% of the main wing area.

Combined Parts: To reduce costs, this prototype used the nose section from a Douglas A-4 Skyhawk and intakes from a McDonnell Douglas F-4 Phantom II.

Technical Specifications (Design Targets)

According to data from Wikipedia and Aviastar.org, the aircraft's performance targets included:

Maximum Speed: Mach 2.2 to 2.4 (approximately 2,560 km/h).

Engine: One Pratt & Whitney F401-PW-400 afterburning turbofan.

Armament: Planned to carry one M61A1 Vulcan 20mm internal cannon, two AIM-7 Sparrow missiles, and wingtip rails for AIM-9 Sidewinder missiles.

Dimensions: Approximately 13.39 meters long with a wingspan of 8.69 meters.

Failure and Cancellation

Although the technology was considered innovative, the program was ultimately terminated in 1981 for the following reasons:

Lack of Lift: Tests showed that the wing system could only generate 70-75% of the aircraft's total weight, making it impossible to achieve a vertical takeoff without the aid of a towline (untethered).

Technical Issues: Complex air ducting caused a significant reduction in thrust compared to initial estimates.

Strategy Change: The US Navy ultimately preferred conventional fighters like the F/A-18 Hornet and adopted the more proven AV-8B Harrier II VTOL aircraft.

The JF-17 Thunder

 The JF-17 Thunder (also known as the FC-1 Xiaolong in China) is a light, single-engine multirole fighter aircraft jointly developed by the Pakistan Aeronautical Complex (PAC) and the Chengdu Aircraft Corporation (CAC) of China.

The aircraft was designed to be a cost-efficient air defense solution, capable of performing a variety of missions, from air interception and ground attack to reconnaissance.

𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭:

In 1999, China and Pakistan signed a formal agreement to develop the aircraft, which was later designated FC-1 (Fighter China-1) by China and JF-17 (Joint Fighter-17) by Pakistan.

The first prototype (PT-01) successfully performed its maiden flight in Chengdu, China, on August 25, 2003.

The first aircraft arrived in Pakistan in March 2007 as a Pakistan Day gift. Local production began at the Pakistan Aeronautical Complex (PAC), and the first Pakistani-built aircraft was delivered to the Pakistan Air Force in November 2009.

Multirole: Designed for air-to-air and air-to-surface combat, with the ability to operate in various weather conditions.

4.5 Generation Technology: The latest variant, Block III, is equipped with an Active Electronically Scanned Array (AESA) radar, advanced electronic warfare systems, and long-range missile (BVR) capability.

Engine Performance: Powered by a single turbofan engine (such as the Klimov RD-93), it can reach a maximum speed of Mach 1.6.

Armament: Features seven hardpoints for various missiles (such as the PL-12 or SD-10), laser-guided bombs, anti-ship missiles, and an internal 23mm cannon.

Cost Efficiency: Known as a "market disruptor" due to its significantly lower price compared to Western fighters like the F-16, while still offering competitive combat capabilities.

Current Operators: Pakistan, Myanmar, Nigeria, and Azerbaijan.

Potential Buyers: As of February 2026, Indonesia was reportedly evaluating the potential acquisition of approximately 40 JF-17s as part of its air defense modernization program. Other countries, such as Bangladesh and Libya, have also expressed similar interest.

The sinking of HMS Sheffield (D80)

 The sinking of HMS Sheffield (D80) on May 4, 1982, was one of the most shocking moments of the Falklands War, marking the first time a British warship had been sunk by enemy attack since World War II.

On the morning of May 4, two Argentine Super Étendard fighter jets detected the British task force. They flew low to avoid radar and fired two AM39 Exocet anti-ship missiles from a range of approximately 20 miles.

One of the missiles struck HMS Sheffield amidships just above the waterline. The missile's explosion (or its remaining fuel) created a large hole and ignited a massive fire that quickly spread across the deck.

The impact damaged the water main, preventing the crew from effectively fighting the fire. Thick, black smoke enveloped the ship, forcing Captain James "Sam" Salt to give the order to abandon ship after four hours of battling the blaze.

A total of 20 crew members were killed in the initial attack, most of them in the galley and computer rooms, while 26 others were injured.

While awaiting evacuation by the HMS Arrow, the surviving crew members legendaryly sang "Always Look on the Bright Side of Life" from the Monty Python film to boost their morale.

Although they survived for several days, the HMS Sheffield ultimately sank on May 10, 1982, in a storm while being towed by the HMS Yarmouth to South Georgia.

This loss forced Britain to change its air defense tactics and recognize the serious threat posed by Argentina's French-made Exocet missiles.

These missiles also sank the British logistics ship Atlantic Conveyor on May 25, 1982, during the Falklands War.

The sinking of HMS Coventry (D118)

 The sinking of HMS Coventry (D118) on May 25, 1982, was one of the most dramatic events of the Falklands War. The Type 42 destroyer sank in just 20 minutes after being attacked by Argentine fighter jets.

Here is the chronology and details of the incident:

Decoy Mission: HMS Coventry was stationed north of Falkland Sound alongside the frigate HMS Broadsword to act as early detection and decoy aircraft to draw Argentine aircraft away from the main fleet in San Carlos Bay.

Air Attack: On the afternoon of May 25—Argentina's national day—two waves of A-4 Skyhawk jets attacked from the mainland. Flying very low over the ground, the ships' radars had difficulty locking on to their targets with their Sea Dart missiles.

Technical Problems: During the second wave, HMS Broadsword had a chance to lock on to its target with its Sea Wolf system, but the maneuvering HMS Coventry suddenly found itself directly in the line of fire, causing the Broadsword's system to lose target lock.

Bomb Hit: Three 1,000-pound bombs struck the ship's port side. Two of the bombs exploded, destroying the forward operating and engine rooms, causing massive, uncontrolled flooding.

Sinking: As a result of the catastrophic damage, the ship immediately listed and capsized. Nineteen crew members were killed (some sources say 20-21) and 30 others were injured.

Evacuation: Approximately 280 crew members were rescued by HMS Broadsword and helicopters in the freezing waters of the South Atlantic.

The loss of HMS Coventry occurred on the same day as the Atlantic Conveyor, known as "Black Tuesday" in the Royal Navy.
