The designation OQ-5 was allocated to a small target drone similar to the Radioplane OQ-2A with a wingspan of about 3.6 m (12 ft). Most likely it was intended to complement the OQ-2/-3 production by Radioplane and Frankfort, but was cancelled when the latter eventually produced enough targets. Source  doesn't name a contractor, so it's possible that none had been selected before the OQ-5 was cancelled.
I have no further details on the configuration of the OQ-5.
