The Ariane 5 reused the code from the inertial reference platform from the Ariane 4, but the early part of the Ariane 5's flight path differed from the Ariane 4 in having higher horizontal velocity values. This caused an internal value BH (Horizontal Bias) calculated in the alignment function to be unexpectedly high.
The first flight of the Ariane V rocket self-destructed due to an overflow occurring during a floating-point to integer conversion in the on-board guidance software. The same software had been used successfully in the Ariane IV program, but the Ariane V produced larger values for some variable, causing the overflow. [31] [32]
Only recently have Ariane 5 launches become as reliable as those of the predecessor model. This doesn't seem right. 3 failures in 107 launches is a 2.8% failure rate; 4 in 36 launches to date is 11.1% (or generously, counting only complete failures, 5.5%).
The Ariane 5 ME (Mid-life Evolution) was in development into early 2015, and was seen as a stopgap between Ariane 5ECA/Ariane 5ES and the new Ariane 6. With first flight planned for 2018, it would have become ESA's principal launcher until the arrival of the new Ariane 6 version.

Ariane flight VA256 was an Ariane 5 rocket flight that launched the James Webb Space Telescope (JWST) into space on 25 December 2021. [3] It was 2021's final Ariane flight, its most valuable payload to date, and the 256th Ariane mission. The launch was described by NASA as "flawless" and "perfect". [4]
