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, intelligence, surveillance and reconnaissance), fire support and electronic warfare and ground-attack 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, Italy, Greece, Bulgaria, Lithuania, Mexico, Morocco, Romania, Peru, and Slovakia.

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 four-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. 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.
