That concluded the Navy’s participation in the program. In accordance with Cdr Metsger: “Our flights, including simulated service approaches and landings, assured us that sweeping the wings wouldn’t adversely affect service operations. L-39-2 was repurposed in mid 1946 to assist Bell’s X-2 program. The wing was modified to represent a swept wing with a circular-arc airfoil and the leading edge was prolonged ahead to the side of physique. Bell engineering failed to understand the aerodynamic implications of a planform change. The center of elevate was shifted far sufficient forward that the test pilot made most of the brief flight on 20 July 1946 with full forward stick. Following reballasting, including reinstatement of the heavier 4-bladed propeller, it was utilized by Bell for low-pace handling qualities and efficiency analysis of the X-2 wing. L-39-2 was ferried to NACA Langley on eleven December, the place it remained for 3 years. In December 1949, each aircraft were reportedly transferred to NACA Lewis the place they had been scrapped.

Singapore will announce in the following few months plans to replace its ageing F-16 fighter jets, its protection minister mentioned, listing a lot of manufacturers that could be in the running for a deal potentially worth billions of dollars. With Southeast Asia’s largest defence finances, the rich city-state is a key prize for global arms companies because it seems to spend money on new expertise and improve its gear. “Whether it’s Typhoons, whether it’s F-35s, whether or not it’s Sukhois, even now Chinese language-made stealth fighters. I mean these are the usual suspects that you have to have a look at,” Ng mentioned. He was referring to the Eurofighter Typhoon that’s built by Britain’s BAE systems and F-35s from U.S.-based mostly Lockheed Martin. Sukhoi is a Russian producer. A hundred million depending on the producer. Singapore should make a decision in the following few months “to make sure that we will substitute our F-16s in time,” Ng added. Singapore’s F-16s first entered service in 1998. The country has usually used U.S.-made aircraft previously, making the F35s – a variant of which appeared at town-state’s airshow again in February – a seemingly successor.
