The use of accelerated corrosion testing has become more widespread to demonstrate the ability of materiel to have long-term corrosion resistance.  These tools have primarily been developed around commercial automotive and infrastructure elements.  To understand their ability to predict performance on military vehicles and weapon systems a comparison between laboratory and field tests is needed.  This paper provides a review of harsh marine exposure performance as compared to several common accelerated corrosion tests to demonstrate the ability of these to generally rank material performance and any correlation between the test environments.
