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 the former 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.

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. 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.
