The Lavochkin La-15 (NATO reporting name 'Fantail'), initially designated La-174, was an early Soviet jet fighter and a contemporary of the Mikoyan-Gurevich MiG-15.

Development
The La-15 was the outcome of a series of development aircraft that began with the Lavochkin "168" (La-168) in 1947 and continued with the "176" (La-176) later in 1948. The Lavochkin La-168 was a jet fighter developed for the USSR.

Please see WikipediaWikiProject Aircraft/page content for recommended layout The Derwent-powered La-174 (initially called just "174") was designed as a backup for the main program of Nene-powered La-168, in case the British failed to deliver stronger afterburned Nene engine. The first prototype of La-174 was flown just 9 days after its counterpart MiG-15, on January 8, 1948. WikipediaWikiProject Aircraft.

Trials were continued with an improved second prototype, designated "174D". From August to September 25, 1948 it underwent state trials. In comparison with the Nene-powered MiG-15 it had almost the same maximum speed and better maneuverability, with somewhat reduced rate of climb. Even while the second prototype of La-174 was undergoing flight trials in August, the type was ordered into production in September 1948. In April 1949 it was given an official military designation La-15. This is a list of Aviation -related events from 1949: Events Aerolíneas Argentinas established
The La-15 had a barrel-like fuselage, swept wings, and stabilizers mounted high on the fin, almost like a T-tail, all features that gave it a surprisingly close resemblance-especially including the landing gear setup-to the never-built Focke-Wulf Ta 183 German second generation jet fighter design. A T-tail is an aircraft tail stabilizer arrangement in which the horizontal surfaces ( Tailplane and elevators are mounted to the top of the WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout In basic configuration, it resembled the more famous MiG-15, except for a slightly sleeker appearance and high-mounted wings. It was popular with pilots because of its easy handling and dependability, and its pressurized cockpit was an advantage at high altitude. Pressurization generally refers to the application of Pressure in a given situation or environment and more specifically refers to the process by which Atmospheric pressure Nevertheless, official enthusiasm for the La-15 was mild, largely because it was a complex design that required complicated (and expensive) production tooling. With an arrival of the Klimov VK-1 engine (improved Nene), the Soviet authorities decided to produce only one fighter, and they chose the MiG-15bis, despite newest Lavochkin's fighters La-168 and La-176 with VK-1 engine, basing upon the La-15, had better performance.

235 La-15s were built, and served with the Soviet Air Force until 1954.
