SIAI-Marchetti S.211

The SIAI-Marchetti S.211 (later Aermacchi S-211) is a turbofan-powered military trainer aircraft designed and originally marketed by Italian aviation manufacturer SIAI-Marchetti.

SIAI-Marchetti started to develop the S-211 in 1976 as a private venture initiative, announcing its existence during the following year. In April 1981, the first prototype performed its maiden flight. The Singapore Air Force placed the first order for ten aircraft in 1983. Some 60 aircraft have been sold to air forces around the world. Following Aermacchi's purchase of SIAI-Marchetti in 1997, the former has held the production rights to the type. An extensively redesigned and modernised derivative, the Aermacchi M-345, has been developed by Alenia Aermacchi, and entered service in 2020.

Development

In 1976, Italian aircraft company SIAI-Marchetti began work on what would become the S-211. The project was undertaken as a private venture to develop a new basic trainer aircraft. SIAI-Marchetti planned to offer the type to the company's existing customer base, consisting of various air forces around the world that operated their SF.260, a piston-engined trainer. The programme's existence was announced in Paris in 1977. Reportedly, customer interest was strong enough to justify the construction of two prototypes, the first of which flew on 10 April 1981. In 1983, the Singapore Air Force placed the first order for the S-211, for ten aircraft.

The S-211A was a slightly modified and updated variant of the S-211, was a losing contender in the United States Air Force's Joint Primary Aircraft Training System (JPATS) aircraft selection. Among the seven aircraft to enter, the Raytheon/Pilatus entry emerged as the winner, being produced as the T-6 Texan II. The S-211 team was initially partnered with American aircraft company Grumman. Following its merger with Northrop Corporation in 1994, SIAI-Marchetti worked with Northrop Grumman on the S-211A up until the selection.

In 1997, rival Italian aviation firm Aermacchi acquired SIAI-Marchetti and thereby the S-211. According to Aermacchi, the acquisition would enable significant cost savings in production following consolidation to its Venegono Inferiore facility. Aermacchi has continued to seek customers for the type. In 2004, the company announced its intention to develop an improved version of the S-211, then referred to as the S-311, later as the M-345. At the time, Aermacchi was also developing the M-346 Master, which serves as a lead-in fighter trainer. While vaguely similar to the M-211, the M-346 is considerably larger and intended to perform both the basic and advanced training syllabus, as well tactical training functions, as an alternative to single-engined turboprop-powered competitors.

The avionics of the S-211 were designed to be customisable, allowing the manufacturer to accommodate a customer's various mission requirements. Since entering service the S-211 fleet has functioned both as a trainer and in offensive operations via secondary attack capability. These were redesignated as AS-211s and nicknamed as "Warriors". Following the retirement of the PAF's last Northrop F-5 fighters in 2005, the additional task of air defense has been assigned to its AS-211s. Because of this, the PAF initiated some improvements to the AS-211s to improve its combat capability through a series of programs and innovations.

The first program was called "Project Falcon", which installed the Norsight Optical Sight previously fitted to withdrawn F-5s into the AS-211. The program was initiated by Lieutenant Colonel Enrique Dela Cruz, the Group Commander of the 5th Tactical Fighter Group.

In July 2022, the remaining S-211s are being used for training as the FA-50s are brought into service.

Variants

;S-211: Original production version with total of approximately sixty built. Was operated by the air forces of Haiti, Philippines and Singapore.

;S-211A: Proposed version developed with input from Grumman for the JPATS (two prototypes, converted from two former Haitian S-211 aircraft). 25 aircraft delivered, including one partially completed airframe for spare parts and 15 assembled locally by Philippine Aerospace Development Corporation.

Haitian Air Force (HAF) – Four aircraft were delivered in June 1985, they were retired and put up for sale on 23 April 1990.

;

Republic of Singapore Air Force (RSAF) – total of 32 aircraft including 24 assembled locally by Singapore Aircraft Industries and two former Haitian aircraft were acquired as attrition replacements. After retirement, four were shipped back to Singapore being preserved for museum display and as educational/instructional airframes, while the remaining 21 airframes, including one airframe that had been used for spare parts, were sold off to International Air Parts (IAP) Group Australia Pty Ltd in 2009.

Civilian operators

21 ex-RSAF S-211s were retired and sold to the IAP Group Australia in December 2009, including a cannibalised airframe. Fifteen have since been sold off and placed on the Australian civil registry.

Accidents and incidents

On 14 January 2002, Philippine Air Force S-211 #017 crashed into houses inside the National Food Authority compound in Brgy. M.S.Garcia, Cabanatuan City, Nueva Ecija, due to mechanical problems after making several low passes over Cabanatuan during a contact proficiency flight from Basa AB. Both pilots and 3 civilians on the ground were killed.
On 26 November 2007, Philippine Air Force S-211 #804 went missing after it failed to return to Palawan base after a security patrol and search mission over the disputed Kalayaan Islands in the south China sea, both pilots still missing and their fate remains unknown.
On July 19, 2010, Philippine Air Force S-211 #024 crashed in Concepcion, Tarlac. The 2 pilots, Maj. Wilfredo Donato and 1Lt. Jose Wilbert Leonides Martinez, ejected and landed safely. The aircraft was reportedly low on fuel, which could have caused the crash.
On 28 April 2011, Philippine Air Force S-211 #020 crashed in Bagac, Bataan, after making several aerobatic maneuvers over the shoreline during a contact proficiency flight from Clark Air Base. Investigators later found out that the aircraft entered into a high-G recovery maneuver from a loop that caused the engine to go into a high-G stall and crashed less than a hundred meters from the shoreline with no survivors.

On 19 November 2023, two civilian registered, VH-DQJ and VH-DZJ, S-211 aircraft collided mid-air above Port Phillip Bay, offshore from Mount Martha in Victoria, Australia. One aircraft (VH-DQJ) safely landed at Essendon Airport, while the other aircraft crashed into the water in Port Phillip. On 21 November, TV presenter Charley Boorman identified the two persons on board, one a photographer with whom he had worked; and, police announced that the main part of the crashed aircraft had been found in Port Phillip Bay.
