To my knowledge MoD had not laid steel for the lead ship yet which is scheduled next fiscal year.Launch is scheduled fiscal year 2018 and will be commissioned in 2020. The second ship schedule is 2018 steel to be laid, Launch in 2019 and commission in 2021.
They will be equipped with AEGIS system baseline 9C and AEGIS BMD 5.1
I believe they will be fitted with the SM-3ⅡA.
Beyond that your guess is good as mine.
Fast for 27DD, in a year.
