Is it not true that the Nimrod MRA4 is replacing the retiring R1?
The RC-135 is planned to replace the Nimrod R.1. The reporting as of a few months ago has the R.1 being retired next year with the crews moving onto USAF RC-135s. The plan is for the RAF to receive RC-135s during 2014.
'An MoD spokesman said that between "2011 and 2014, the U.K. will enter into a partnering arrangement with the U.S. that will safeguard U.K. personnel core competencies."
