A Homecoming to USS STETHEM: Nearly 30 Years Later

The first ship I served on was USS STETHEM (DDG 63), when she was one of the newest ships in the fleet. I was on her initial deployment in 1997 as CTR3 Abramowitz. I am in San Diego this week on leave and reached out to request a visit of STETHEM and want to thank her CO, CDR Mike Walker, and all the “Steelworkers” who welcomed me aboard. Very gracious and accommodating for a sentimental return for CAPT Abramowitz nearly 30 years later. It was a great moment of reflection and I wish all past, present, and future DDG 63 Steelworkers the best – STEADFAST AND COURAGEOUS!
