Development
The Eurocopter EC635 was developed to meet a Portuguese Army requirement for a fire support and medical evacuation helicopter to support its plans for a specialist Army Air Corps unit — UALE. The EC635 was first revealed at the Aviation Africa exhibition in May 1998 and the Portuguese Ministry of Defence subsequently signed an agreement for nine EC635 T2 helicopters equipped with Turbomeca Arrius 2B2 engines, at a cost of €35 million in October 1999. Delivery of the first Portuguese aircraft was expected to begin in 2001; however, continual delays in production led to the Portuguese Ministry of Defence canceling the contract in August 2002, citing Eurocopter's failure to deliver all aircraft between August 2001 and April 2002 as the reason. Eurocopter claimed that disagreements over the integration of weapons systems on the helicopter were the reason for the cancellation.
The Royal Jordanian Air Force agreed to purchase the 9 Portuguese helicopters in October 2002 and the first aircraft was delivered in July 2003. Jordan ordered a further 4 helicopters in January 2006 and deliveries of all machines were completed in 2007.
In April 2006, the Swiss Defence Procurement Agency (Armasuisse) ordered 20 EC635's for the Swiss Air Force, to replace the aging Aérospatiale Alouette III in performing transport and advanced training missions. The first four aircraft will be built by Eurocopter, with the remaining 16 being built by RUAG Aerospace in Alpnach, Switzerland, and deliveries expected to be completed between March 2008 and December 2009.

Famous quotes containing the word development:
“There are two things which cannot be attacked in front: ignorance and narrow-mindedness. They can only be shaken by the simple development of the contrary qualities. They will not bear discussion.”
—John Emerich Edward Dalberg, 1st Baron Acton (1834–1902)
“The young women, what can they not learn, what can they not achieve, with Columbia University annex thrown open to them? In this great outlook for women’s broader intellectual development I see the great sunburst of the future.”
—M. E. W. Sherwood (1826–1903)
“I hope I may claim in the present work to have made it probable that the laws of arithmetic are analytic judgments and consequently a priori. Arithmetic thus becomes simply a development of logic, and every proposition of arithmetic a law of logic, albeit a derivative one. To apply arithmetic in the physical sciences is to bring logic to bear on observed facts; calculation becomes deduction.”
—Gottlob Frege (1848–1925)
