the frame of six separate PEACE VECTOR programs. In March 2010 it was announced that Egypt would purchase an additional 20 Block 52 aircraft (16 F-16Cs and four F-16Ds). The Egyptian Air Force operated 220 F-16s at that point, making it the world's fourth largest F-16 operator. Four of the F-16s ordered were delivered on 3 February 2013, raising the number of aircraft delivered to 224. The remaining 16 were to be delivered through 2013. Following the 2013 Egyptian coup d'état, the Pentagon had said deliveries of the jets would continue. On 24 July 2013 however, President Barack Obama announced the F-16 deliveries would be halted due to continuing political unrest. In March 2015 the US announced the resumption of the deliveries of the F-16s, the last of which was delivered in October 2015. Israel The Israeli Air Force (IAF) is the second largest user of the F-16 Fighting Falcon, second only to the U.S. Air Force and its reserve components. The IAF achieved the type's first air-to-air victories when its F-16s shot down two aircraft, a Mil Mi-8 helicopter and a Mikoyan-Gurevich MiG-21 fighter plane, both Syrian, in April and July 1981 respectively. The IAF took delivery of its first F-16s earlier than expected after the cancellation of the sale of F-16s to the Iranian Air Force. The IAF had announced plans to buy 75 F-16s as early as 1978, and deliveries were carried out under American Foreign Military Sales program Peace Marble I. These F-16A/Bs received the Hebrew nickname "Netz" (Hawk). Peace Marble II witnessed the delivery of a further 75 block 30 F-16C/Ds to the IAF. Israel's F-16 fleet was further expanded by Peace Marble III, which brought 30 block 40 F-16Cs and 30 two-seat F-16Ds to the IAF between 1991 and 1993. These newer models were nicknamed "Barak" ("lightning"). In part to reward Israel for its restraint during the Gulf War, a shipment of 50 US-surplus F-16As and F-16Bs were delivered in 1994. In a deal worth $4.5 billion, Israel also ordered 102 additional block 52+ F-16Ds, designated F-16I and nicknamed "Sufa" (Storm). Deliveries of these took place between 2004 and 2009. In July 2013, Israel began a program called Teuza (boldness) for the purpose of turning some military bases into sales lots for obsolete IDF equipment. Older F-16 models would be sold off, or sold for scrap if there were no buyers. Main buyers were
