IXR-2 All versions

This is the complete family of IXR-2 rockets (previously TX-2)

The rockets are placed in order of payload capacity with the first rocket being a remake of the MKI with an approximate payload capacity of 17.5 tonnes.

The 2nd and 3rd rockets are the MKII and the MKII B (with updated boosters) with approximate payload capacities of 20 and 25 tonnes .

rockets 3 and 4 are the MKVIII and MKVIII B which can handle 25 and 45 tonnes respectively

and last are the most capable rockets the MKVII and the MKVII B (with updated boosters taken from Capricorn MKI) which can handle 50 and 90 tonnes respectively.

The IXR-2 family is one of if not the longest surviving design i've made (the only ones that are similar in age are PeaceLauncher and technically Scorpio but the MKII looks basically nothing like the original, maybe the Son Of Scorpio rockets though) and have stayed virtually identical throughout the generations with only minimal changes to the design such as engines and most recently a fairing swap.
