In August 2013, Carmack indicated that following the crash of the STIG-B rocket earlier that year, he had wound down the company operations and had put the company in "hibernation mode." Armadillo had stopped accepting (profitable) contract R&D work two years prior, in order to focus on development of a suborbital reusable rocket. During those two years, Armadillo operated at an approximately US$1 million per year burn rate funded personally by Carmack. Several reasons were offered for this outcome, including a failure to adopt a multi-test-vehicle build strategy, making the loss of a single rocket more significant than it would have otherwise been.
