Topband: Detuning Relay Flyback Diode

I have a couple of 6ms 12V Kilovac relays wired up as a detuning circuit
during RX.  One question comes up before implementation regarding flyback
diodes - would they be needed?  Seeking opinions on this question.  The
relays are powered during TX and not powered for RX direct keyed by the
radio with no sequencer.
