Singapore Government quietly expanding F-15 fleet from 24 to 40, rumored to have acquired unmanned aerial drone from Israel

Singapore appears to have quietly boosted the size of its F-15SG fleet from 24 aircraft to 40, according to Boeing financial statements, aircraft registration filings, and US congressional reports.
Singapore originally bought 12 F-15SGs - with an option for eight more - under a contract signed in December 2005. In October 2007 the city-state modified this option by buying 12 more to give it a total of 24.
One retired armed forces officer told IHS Jane's that this was a strategic decision to keep its neighbours guessing, and also because the country's leaders did not need to use military procurement as a populist crutch.
However, this refusal to confirm acquisitions can occasionally lead to surreal conversations with military and defence industry officials, such as at the 2012 Singapore Airshow, when Israeli officials would not confirm the sale of IAI Heron unmanned aerial vehicles to Singapore despite the presence of one on static display at the show.
