Mcdonnell F3H-2 Demon

As the original Westinghouse J40 engine turned out to be disappointing, the subsequent Demons were powered by the Allison J71 engine which also powered the Douglas B-66 Destroyer and were named F3H-2N. However, the J71 engine proved to be troublesome too for an airplane of the Demon's size as it suffered from frequent flameouts and compressor stalls. The first F3H-2N flew for the first time in October 1954. There was another serious problem, the ejection seats weren't reliable enough and they had to be replaced by Martin-Baker ones, which had been becoming in the standard ones in the United States Navy due to their higher reliability, specially at low altittudes.
In spite of all those problems, the navy ordered 239 of them, which were deployed in March 1956.
