C-27J Spartan

The Alenia C-27J Spartan is a military transport aircraft developed and manufactured by Leonardo's Aircraft Division (formerly Alenia Aermacchi until 2016). It is an advanced derivative of Alenia Aeronautica's earlier G.222 (C-27A Spartan in U.S. service), equipped with the engines and various other systems also used on the larger Lockheed Martin C-130J Super Hercules. In addition to the standard transport configuration, specialized variants of the C-27J have been developed for maritime patrol, search and rescue, C3 ISR (command, control, communications, intelligence, surveillance and reconnaissance), fire support/ground-attack and electronic warfare missions.

In 2007, the C-27J was selected as the ''Joint Cargo Aircraft'' (JCA) for the United States military; these were produced in an international teaming arrangement under which L-3 Communications served as the prime contractor. In 2012, the United States Air Force (USAF) elected to retire the C-27J after only a short service life due to budget cuts; they were later reassigned to the U.S. Coast Guard and United States Special Operations Command. The C-27J has also been ordered by the military air units of Australia, Bulgaria, Chad, Greece, Italy, Kenya, Lithuania, Mexico, Morocco, Peru, Romania, Slovakia, Slovenia, Zambia and an undisclosed country.

Design and development

In 1995, Alenia and Lockheed Martin began discussions to improve Alenia's G.222 using C-130J's glass cockpit and a more powerful version of the G.222's T64G engine and three-blade propellers. In 1996, a program began on an improved G.222, named C-27J; it used a U.S. military type designation based on the G.222's C-27A designation. In 1997, Alenia and Lockheed Martin formed Lockheed Martin Alenia Tactical Transport Systems (LMATTS) to develop the C-27J. The design changed to use the C-130J Super Hercules's Rolls-Royce AE 2100 engine and six-blade propeller.Frawley, Gerald. "LMATTS C-27J Spartan". ''The International Directory of Military Aircraft, 2002/2003''. Fishwyck, ACT: Aerospace Publications, 2002. . Other changes include a fully digital MIL-STD-1553 systems and avionics architecture, and an updated cargo compartment for increased commonality. The C-27J has a 35% increase in range and a 15% faster cruise speed than the G.222.

The C-27J first flew on 24 September 1999. Two months later, the Italian air force was reported as the launch customer of the C-27J, ordering 12 Spartans. At the time, the C-27J had a basic price of US$24 million. After over 400 hours of flight tests spanning less than 13 months, the aircraft was granted civil certification by the Italian Civil Aviation Authority at the Paris Air Show in June 2001. Military certification followed on 20 December 2001.

By 2005, the U.S. Army had identified the need to replace its aging Short C-23 Sherpa lifter. In lieu of adequate fixed-wing airlift availability, the CH-47 helicopter fleet was being worked hard on the "last tactical mile" to supply forward-placed troops; thus the U.S. Army sought the C-27J for its direct support capabilities, and to reduce demands on the CH-47 fleet.Weisgerber, Marcus
"C-27J battle splits Air Force, Guard."
''Air Force Times,'' 5 December 2011. In 2006, LMATTS was dissolved when Lockheed Martin offered the C-130J in 2006 as a contender in the same U.S. Army and U.S. Air Force Joint Cargo Aircraft (JCA) competition in which the C-27J was competing. Alenia Aeronautica then paired with L-3 Communications, forming the Global Military Aircraft Systems (GMAS) joint venture to market the C-27J; Boeing also joined GMAS.

GMAS bid the C-27J in the JCA competition against Raytheon and EADS North America's C-295 to replace existing Short C-23 Sherpa, Beechcraft C-12 Huron and Fairchild C-26 Metroliners in the Army National Guard, and as a substitute tactical airlifter for Air National Guard groups or wings losing C-130s to retirement or Base Realignment and Closures.Putrich, Gayle S
"C-27J tapped for Joint Cargo Aircraft."
''Air Force Times'', 13 June 2007. By November 2006, the C-27J completed the U.S. Department of Defense's Early User Survey evaluations, having flown a total of 26 hours and surpassed all requirements. GMAS also announced that the C-27J will be assembled at a facility at Cecil Field, Duval County, Florida. The JCA's final selection was expected in March 2007, however it was postponed until 13 June 2007, when the Pentagon announced the award of a US$2.04 billion contract for 78 C-27Js, including training and support, to GMAS.Gettle, Master Sgt. Mitch
"C-27J Spartan named as Joint Cargo Aircraft."
''Air Force Public Affairs'', 14 June 2007.

On 22 June 2007, Raytheon formally protested the JCA contract award for the C-27J. On 27 September 2007, the GAO announced that it had denied Raytheon's protest, thereby allowing the Pentagon to proceed with procurement; at this time, the U.S. Army had requirement for up to 75 aircraft in the Army National Guard; the Air Force had a requirement for up to 70 aircraft in the Air Force Special Operations Command and the Air National Guard. The first C-27J was planned to be delivered to the joint U.S. Army–Air Force test and training program in June 2008. The first flight of a U.S. C-27J occurred on 17 June 2008.

In November 2020, Leonardo launched the C-27J Next Generation programme with new equipment, systems and aerodynamic solutions to improve operating efficiency and enhance performance. The New Generation features comprehensive new avionics to comply with the Performance Based Navigation international standard to operate in civil air space without limitations and to enhance interoperability in tactical scenarios. While the new winglets contribute to improve climb performance and increase the MTOW by up to 1,000 kg.

Operational history

United States

The United States received its first C-27J on 25 September 2008. In September 2008, L-3 Link's C-27J schoolhouse officially began classes at the Georgia Army National Guard Flight Facility, Robins Air Force Base, Georgia. By April 2009, the U.S. Army had accepted deliveries of 2 aircraft and had 11 more on order.Trimble, Stephen

''flightglobal.com'', 22 March 2009. In May 2009, the U.S. Army and Army National Guard relinquished all aircraft to the U.S. Air Force, primarily the Air National Guard; this led to the purchase being reduced to 38 C-27Js and the USAF receiving total control of all US C-27Js. Initially, the C-27J was to be operated by the Air National Guard for direct support of the United States Army; later, both Army National Guard and Air National Guard flight crews support the aircraft's fielding. By July 2010, the U.S. Air National Guard had received four C-27Js for testing and training, with initial operational capability expected in October 2010.Scully, Megan
"The Little Airlifter That Could."
''Air Force magazine'', Volume 93, July 2010. Retrieved: 29 July 2018.

The U.S. Air Force performed the C-27J's first combat deployment in summer 2011. In August 2011, two C-27Js flown by Air National Guard aircrews, augmented with Army National Guard personnel, began operations at Kandahar Air Field, Afghanistan. Between August 2011 and June 2012, the C-27Js of the 179th Airlift Wing, followed by the 175th Wing, executed more than 3200 missions transporting over 25,000 passengers, and 1400 tons of cargo. Via tactical control of the C-27Js, the U.S. Army was able to employ helicopters more efficiently, splitting missions between the two platforms based on their relative strengths.

On 26 January 2012, the Department of Defense announced plans to retire all 38 USAF C-27Js on order because of excess intra-theater airlift capacity and budgetary pressures; the C-130 would perform its functions. In February 2012, Alenia warned that it would not provide support for C-27Js resold by the US to international customers in competition with future orders. On 23 March 2012, the USAF announced the C-27J's retirement in fiscal year 2013 after determining other programs' budgetary needs and requirement changes for a new Pacific strategy."C-27 program cut explained, budget aligned with strategy"
''Air Force'', 30 March 2012. The cut was opposed by the Air National Guard and by various legislators.

In July 2012, the USAF briefly suspended flight operations following a flight control system failure. By 2013, newly built C-27Js were being sent directly to the Davis–Monthan Air Force Base boneyard. The USAF spent $567 million on 21 C-27Js since 2007, with 16 delivered by the end of September 2013; 12 had been taken out of service while a further 5 were to be built by April 2014 as they were too near completion to be worth cancelling. Budget cuts motivated the divesture; a C-27J allegedly costs $308 million over its lifespan in comparison with a C-130's $213 million 25-year lifespan cost.

In November 2012, the C-27J deployed for its first domestic mission, contributing to the Hurricane Sandy relief effort.

In July 2013, the U.S. Coast Guard considered acquiring up to 14 of the 21 retired C-27Js and converting them for search-and-rescue missions, while cancelling undelivered orders for the HC-144 Ocean Sentry to save $500–$800 million. EADS claimed that the HC-144 costs half as much as the C-27J to maintain and operate. The U.S. Forest Service also wanted 7 C-27Js for aerial firefighting. The U.S. Special Operations Command (SOCOM) were interested in acquiring ex-USAF C-27Js. If the DoD determined it could not afford the aircraft, they would go to the Forest Service. In late 2013, SOCOM was allocated 7 C-27Js to replace its CASA 212 training aircraft. In December 2013, the 14 remaining C-27Js were transferred to the Coast Guard, with the first HC-27J delivered in Coast Guard colors in April 2016.

Others

In October 2006, Italy accepted delivery of the first C-27J of an initial batch of 12 aircraft and in January 2007, the first aircraft was delivered to the 46^a Brigata Aerea, in Pisa. From 12 September 2008 to 27 January 2009, a pair of Italian Air Force C-27Js were deployed to Afghanistan to contribute to NATO in-theatre airlift operations. In December 2013, an Italian C-27J was deployed to the Philippines to participate in international humanitarian relief operations in the aftermath of Typhoon Haiyan. The Italian Air Force is also the launch customer for a special mission variant of the C-27J, named Praetorian in the configuration tailored for ItAF and equipped with ISR equipment and roll-on, roll-off mission systems consoles; Italy is the first European nation to operate such an aircraft.

In 2006, Bulgaria had initially ordered five C-27J to replace its aging fleet of Antonov An-26 aircraft, but reduced its order to three aircraft in 2010 due to funding shortages."Alenia Aeronautica delivers the first C-27J to the Bulgarian Air Force."
''Alenia Aeronautica,'' 13 November 2007.Hoyle, Craig

''FlightGlobal.com'', 31 March 2011. In March 2011, the Bulgarian Air Force received the third and final of the C-27Js ordered; the fleet is employed for military transport missions as well as medical evacuations, special tasks of the Interior Ministry, and participating in international operations such as the rotation of Bulgarian troops in Afghanistan.

In 2006, the Romanian government announced the selection of the C-27J, seeking 7 aircraft to be delivered from 2008 to replace Antonov An-24 and Antonov An-26 aircraft, beating the EADS CASA C-295. In February 2007, a legal challenge filed by EADS blocked the Romanian order; the order was allowed to proceed when the Romanian court rejected EADS' complaint in June 2007. On 7 December 2007, a contract for the seven C-27Js was officially signed. On 12 April 2010, the first two C-27s were delivered to the Romanian Air Force.

In December 2011, the Royal Australian Air Force (RAAF) issued a Foreign Military Sales request for 10 C-27Js valued at US$950m to replace its retired DHC-4 Caribou fleet. Australia had opted for the C-27J over the rival EADS CASA C-295 following a RAAF evaluation, which had noted the C-27J's wider and taller cabin being compatible with the Australian Army's general purpose G-Wagon vehicle, and palletized goods. In December 2013, the first Australian C-27J performed its maiden flight. In December 2014, the RAAF began maintenance training on the type; delivery of the first two of the ten C-27Js on order was also formally accepted that month. The last aircraft for RAAF was delivered in April 2018.

On 6 July 2011, the Mexican Air Force signed a $200 million contract for four C-27Js and a multiyear support agreement for the fleet. The first aircraft was received two months later, all four were delivered by the end of 2012. Mexico's C-27Js are based at Santa Lucía Air Force Base Num 1 and operated by 302 Air Squadron alongside a number of C-130 Hercules.

In June 2013, the Peruvian Air Force was negotiating to acquire four C-27Js for $200 million; future purchases by Peru may increase the total to 12 Spartans. The C-27J competed against the EADS CASA C-295, Antonov An-70, Antonov An-32, and C-130J. On 25 November 2013, Peru selected the C-27J; two aircraft and associated support was purchased in a 100 million-euro deal. On 27 March 2015, the first C-27J was formally accepted by the Peruvian Air Force; by this point a total of four C-27Js were on order for the service. The fourth aircraft was delivered on 5 December 2017 at Grupo Aéreo N°8.

In June 2018, Kenya received an international loan for military aircraft and expansion including three C-27J.

In January 2021, the Slovenian government announced that its interest in purchasing one C-27J for the Slovenian Air Force and Air Defence. On 17 November 2021, the Slovenian Ministry of Defense signed a contract for one C-27J to the Slovenian Army; it is to be delivered within one year and be equipped with modules for transporting casualties, cargo, and extinguishing forest fires.

Possible sales

On 21 August 2009, Taiwan announced that it had entered price negotiations with Alenia Aeronautica for the sale of six C-27Js.

In 2010, the Indian Air Force issued a Request for Information (RFI) for 16 medium military transport aircraft; Alenia Aeronautica responded with data on the C-27J.

In 2011, Indonesia was considering purchasing several C-27Js.

In 2015, Alenia Aermacchi were studying the development of a C-27J maritime patrol variant. Other proposed variants of the platform include a multi-mission C-27J that could be armed with various air-launched weapons and equipped with a maritime surveillance radar; Alenia Aermacchi have promoted this model to the Royal Air Force.Hoyle, Craig
"DSEI: Alenia Aermacchi touts C-27J for UK."
''Flight International'', 18 September 2015.

In 2016, Leonardo conducted demonstration flights around La Paz at the request of the Bolivian government, which may led to Bolivia purchasing C-27Js.

The Ghana Air Force requested four C-27Js via an FMS sale, but the purchase was never completed.

Failed bids

In 2007, the C-27J was being considered as a sole-source C$3 billion contract by Canada as a replacement for its search and rescue air fleet. Alenia Aermacchi bid their C-27J FWSAR/MPA, a modified C-27J for the Search and rescue and Maritime Patrol Aircraft roles. Exclusive modifications included a mission systems pallet from General Dynamics Mission Systems Canada, additional observation windows, an AESA search radar, satellite and ATC radios, flare/markers launchers, an electro-optical/infrared turret, a new flight management system and other performance upgrades. Alenia Aermacchi bid up to 32 aircraft with lifetime maintenance from KF Aerospace and in-service support from General Dynamics Canada. The C-27J FWSAR/MPA bid competed against the Airbus C-295 FWSAR and the Embraer KC-390. In December 2016, the Canadian government selected the C-295.

In 2012, the C-27J was shortlisted as a candidate for the Philippine Air Force (PAF) medium lift aircraft program. A joint team from the Philippines' Department of National Defense (DND) and PAF inspected the C-27J in January 2012. The DND already received approval from the Philippine president to purchase 3 units, and is awaiting congressional approval as of November 2012. However, the PAF announced EADS-CASA's (now Airbus) C-295M as declared winner for the medium lift aircraft acquisition project.

Variants

AC-27J Stinger II

The AC-27J was a proposed gunship for the U.S. Air Force. In 2008, US$32 million was reallocated to buy a C-27J for the U.S. Air Force Special Operations Command, to fulfill requirements defined by AFSOC for the AC-XX concept, a replacement for the aging Lockheed AC-130s.Schanz, Marc V
"Filling the Gunship Gap"
. ''Air Force'' magazine, 18 August 2008. It was to use proven systems to reduce risk. AFSOC planned for 16 gunships, the first in 2011 and two more per year up to 2015. The AC-27J was to be a multi-mission platform, equipped with full-motion cameras and outfitted to support covert infiltration and other ground operations, armed with either a 30-millimeter or 40-millimeter gun or precision-guided munitions such as the Viper Strike bomb.Weisgerber, Marcus. "AFSOC gets ok to buy 16 AC-27 gunships". ''InsideDefense'', 17 October 2008. At the Air Force Association's 2008 conference, it was named "Stinger II" after the AC-119K Stinger.Trimble, Stephen
"AFA-08: AC-27J Stinger II name revealed"
. ''Flight Global blog''. September 2008.

C-27A ''90-0170'' was removed from storage at AMARC in October 2008 and delivered to Eglin AFB, Florida, for use by the Air Force Research Laboratory to test the feasibility of mounting of 30 mm and 40 mm guns. In May 2009, the program was put on hold because U.S. Army funding for 40 C-27s in an Army–Air Force cooperative purchase was removed from the fiscal 2010 budget.LaGrone, Sam
"AFSOC plan for C-27s takes nosedive"
''Air Force Times'', 4 May 2009. U.S. Air Force Special Operations Command elected to standardize their fleet with the C-130 to meet its gunship needs.LaGrone, Sam

''Air Force Times'', 14 May 2009.

HC-27J

The HC-27J is a modified surveillance variant for the US Coast Guard. 14 retired C-27Js were rebuilt as HC-27Js for maritime patrol, surveillance, medium-range search and rescue, drug and migrant interdiction, and disaster response missions. Deliveries began in November 2014.

MC-27J

The MC-27J is a variant for multi-mission purposes, including Command and Control, Communications, Intelligence, Surveillance, Reconnaissance (C3-ISR), Signal Intelligence (SIGINT) and Combat Support operations, using roll-off/roll-on systems for different sensors and equipment: AESA Search Radar; Elettro-Optical/Infra-Red (EO/IR) system; Electronic Support Measures (ESM); palletized Mission System; enhanced Communications System including datalink and SATCOM capabilities; Store Management System to employ Precision Guided Munitions (PGM – one hard point under each wing); palletized fire support system with a high accurate gun able to fire through the LH rear door, that can be installed and rapidly uninstalled when not required. The MC-27J can support special forces and ground troops with direct fire, performing armed ISR, Close Air Support (CAS) and Combat Search And Rescue (CSAR). It also has a defensive aids suite. In 2012, Alenia Aermacchi stated it would offer an upgrade program to the MC-27J configuration. The MC-27J was developed as an Alenia Aermacchi-Orbital private venture.

The Italian Air Force converted three C-27Js into MC-27Js in 2016. On 25 March 2014, the first MC-27J, named Praetorian in the configuration tailored for Italian Air Force, performed its maiden flight. In July 2014, the MC-27J reportedly successfully completed the first phase of ground and flight testing with the Italian Air Force. In October 2020, the annual Documento Programmatico Pluriennale (DPP) 2020-2022 of Italian Minister of Defence indicates realization of the MC-27J to support special operations.

EC-27 "Jedi"

In 2010, the Italian Air Force announced the development of an electronic warfare package for its C-27 fleet under the jamming and electronic defence instrumentation (Jedi) program. One publicised ability of the aircraft is the disruption of radio communications and, in particular, remote detonators commonly used on improvised explosive devices (IEDs). The EC-27 has been compared to the capabilities of the USAF's Lockheed EC-130H Compass Call. In 2015, it was revealed that an improved ''Jedi 2'' payload was under development to provide increased electronic warfare capabilities.
