Sir David Attenborough to launch this recycled fat and tobacco, maybe (5,10)

I believe the answer is:

boaty mcboatface

'sir david attenborough to launch this' is the definition.
(vehicle carried by the RRS Sir David Attenborough)

'recycled fat and tobacco maybe' is the wordplay.
'recycled' is an anagram indicator.
'and' is a charade indicator (letters next to each other) (I've seen this in other clues).
'tobacco'+'maybe'='tobaccomaybe'
'fat' put after 'tobaccomaybe' is 'tobaccomaybefat'.
'tobaccomaybefat' anagrammed gives 'BOATY MCBOATFACE'.

I've seen this clue in The Independent.
