For the past two years, the 377th Test and Evaluation Group has been priviledged to be under the leadership of Commander, Colonel Dustin Harmon. Yesterday, we bid farewell to him and his family, who have provided unwavering support and dedication to the most formidable operation within the ICBM enterprise and the incredible workforce behind its ex*****on. Thankfully, we will continue to benefit from his mentorship in his new role as the 20th Air Force Deputy Commander.

The 377th Test and Evaluation Group welcomes Colonel Janet Dewese as its new Commander. Colonel Justin Secrest, Commander of the 377th Air Base Wing and Presiding Officer over the Change of Command Ceremony, oversaw the assumption of her new title. Under her leadership, we will continue to pursue excellence and ensure the credibility and capability of the Minuteman III weapon system through operational test launches.
