From Doctor Who (new) Series 8, Episode 2, "Into the Dalek":

DALEKS: Seek, locate, destroy. Surrender is not accepted.

And again:

DALEK: Exterminate. Advance. Seek, locate, destroy.
DALEK 2: Seek, locate, destroy.
DALEK 3: Exterminate.

I always assumed that "Seek, locate, destroy" was just a typical Dalekky thing to say, like their second favourite phrase after "Exterminate". Then recently I discovered there's an episode called "Seek, Locate, Destroy" in the TV series Blake's Seven, created by ... Terry Nation, a.k.a. the real-world Davros, a.k.a. the guy who created the Daleks.

Has the Daleks' "Seek, locate, destroy" ever been acknowledged as a Blake's Seven tribute?

  • It's also a Metallica song.

    The Metallica song is just "Seek and Destroy", FWIW.

Blake's 7 was first broadcast 1978. The Daleks first appeared in 1963.

The first occurance of a Dalek saying "Seek, locate, exterminate" I can find was in Destiny of the Daleks (1979), also written by Nation. There may be an earlier one in the same pattern - I don't have searchable scripts to hand.

Occam's razor would suggest it's not a tribute, just that Terry Nation was fond of the phrase in the late '70s. So there would be no particular reason to acknowledge it.

  • "The Chase" has "locate, infiltrate, separate, exterminate," first said by a dalek, then much more fluidly by William Hartnell.
