Alpha Jet MS2, were ordered. The Alpha Jet MS2 bore high levels of similarity to Dassault's proposed Alpha Jet NGEA, featuring a Sagem-built Uliss 81 nav/attack system, a Thomson-CSF-built laser rangefinder and HUD, along with a digital multiplex databus. The Egyptian Air Force used the Alpha Jet MS1 fleet to replace the Aero L-29 Delfín and Mikoyan-Gurevich MiG-15 in the trainer role, while the later-built MS2 standard aircraft served to replace the Mikoyan-Gurevich MiG-17 in the ground-attack role. In February 2000, Egypt was reportedly seeking to replace their Alpha Jet fleet, and was investigating several options, including the BAE Systems Hawk. Civilian service Swiss firm RUAG Aviation offers full support services for the Alpha Jet in cooperation with Dassault Aviation; services provided includes recommissioning, servicing, inspections, system upgrades integration work, along with technical and logistic support. Abbatare Inc. of Arlington, Washington, under the name of "Alpha Jets USA", has imported a number of Alpha Jets into the United States, the firm modifies and sells individual aircraft in the civilian market. Canadian aviation specialist Top Aces operates a fleet of Douglas A-4 Skyhawks and Alpha Jets as adversary aircraft in air combat training exercises; these are often operated under contract for various military clients. Multiple civil aerial display teams have procured Alpha Jets, such as the Flying Bulls and Mustang High Flight Aerobatics teams. H211, a private company which manages the planes owned and leased by Google execs Larry Page, Sergey Brin, and Eric Schmidt, operates a single Alpha Jet, based at NASA's Ames Research Center in Mountain View, California. It is reportedly equipped with scientific instrumentation and used for research purposes. Commencing in the third quarter of 2017, Air Affairs Australia and Discovery Air will provide three Alpha Jets to the Australian Defence Force for Australian Army attack controller training and anti-surface training (simulating sea-skimming missiles) for the Royal Australian Navy. They will be based at RAAF Base Williamtown. Others Considerable foreign sales were expected for the Alpha Jet, with the type becoming available before its main rival, the United Kingdom's BAE Systems Hawk. The two types, being relatively similar in role and specifications, ended up competing for many of the same contracts. This competition led to an aviation commentator stating of the two aircraft: Several other nations also obtained the Alpha Jet E, including the Ivory Coast (seven aircraft), Morocco (24), Nigeria (24), Qatar (six) and Togo (five).
