In the course of its long RAF service, most versions of Lightning were subject to the incorporation of many modifications, mostly without significant external evidence of change. Many were concerned with improving the fire prevention integrity of the engine bays and jet pipes, where the high incidence of fires caused the loss of a high proportion of the Lightnings which were written off in flying accidents.
Modifications to operational equipment were relatively few, because they were not considered cost-effective in an aircraft which was not expected to remain in service for more than a decade! However, limited improvements were made to the AI 23B radar, resulting in the AI 23C and finally AI 23D versions.
