The Nike Apache, also known as Argo B-13, was a two-stage sounding rocket developed by Aerolab, later Atlantic Research, for use by the United States Air Force and NASA.

The TE-307-2 Apache rocket motor was developed by Thiokol as an improvement of its Cajun series of rockets; the Apache was similar in appearance to Cajun, but had an improved propellant that allowed for better performance.

[3] The first launch of Nike-Apache was conducted by the United States Air Force on 17 February 1961.

[1] The Nike Apache was used to carry a variety of payloads to study a wide range of topics including radio astronomy, meteorology, aeronomy, atmospheric conditions, plasma physics, and solar physics.

NASA flew them from Brazil, Canada, India, Norway, Pakistan, Spain, Suriname, Sweden, all across the US, and off of the converted escort carrier USNS Croatan.
