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.

The alignment function was operative for approximately 40 seconds of flight, which was based on a requirement of Ariane 4, but served no purpose after lift-off on the Ariane 5. [4] The greater values of BH caused a data conversion from a 64-bit floating point number to a 16-bit signed integer value to overflow and cause a hardware exception . [ 5 ]

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]
It lacked the high levels of commonality that the Ariane 4 had with its predecessors, and had been designed not only for launching heavier payloads of up to 5.2 tonnes and at a 20 per cent cost reduction over the Ariane 4, but for a higher margin of safety due to the fact that the Ariane 5 was designed to conduct crewed space launches as well ...
For example, an Ariane 42P is an Ariane 4 with two solid-fuel boosters. An Ariane 44LP has two solid, two liquid boosters, and a 44L has four liquid-fuel boosters. Ariane 5 rocket at Le Bourget Air and Space Museum, Paris. Ariane 5 is a nearly complete redesign. The two hypergolic lower stages are replaced with a single LH2/LOX core stage.
Ariane Flight VA245 [1] [2] is the Ariane 5 space launch of BepiColombo that took place on 20 October 2018 at 01:45:28 UTC from the Guiana Space Centre. It was the 101st launch of Ariane 5 (the 5th in 2018), and the 301st Arianespace mission (the 7th in 2018).
