[4] In 1990, ITP acquired an engine maintenance plant located in Ajalvir, Madrid, from Spanish aircraft manufacturer Construcciones Aeronáuticas SA (CASA).

[6] During the 2000s, ITP became involved in the production of the Europrop TP400, the largest turboprop engine developed in Europe, to power the Airbus A400M Atlas, a military transport plane.

[7] By this time, the firm was also engaged in multiple such collaborative defense aero engine programmes, such as EuroJet Turbo GmbH for the EJ200, and MTU Turbomeca Rolls-Royce for the MTR390.

[6] By the mid-2010s, ITP had become the ninth largest aero engine and components manufacturing company in the world in terms of revenue, employing roughly 3,000 people around the globe.

It has been closely involved with Rolls-Royce on the latter's Trent engine family, having acted as a key risk and revenue sharing partner on the programme in addition to applying various turbine-related technologies.

[8] The deal was promoted as increasing Rolls-Royce's long-term aftermarket revenues, along with its stake in various defense-related manufacturing and services programmes, such as the EuroProp consortium that produce the TP400 engine.
