Here are my two cents on your logline
1) staff is for office personnel. Use crew and ditch the word staff.
2) new, state of the art, during its trial run all means the same thing. It's new. Keep only one of the three.
3) is the fact it is a new submarine important for the story? It could just an upgrade or a relaunch. If it's not important, just delete that part.
4) it has been repeatedly mentioned in previous threads on the logline, most people will not have the foggiest idea what PsyOps stand for. An expert in psychological warfare is more telling that the name of the division.
5) more important people who knows what PsyOps stands for will immediately spot the error. PsyOps never do crew evaluation. PsyObs or specialist/consultant psychologist do. Diagnosticians and surgeons both practice medicine. They may even interact together, but they both have completely different jobs.
6) contrarily to what NCIS portrayed, in the real world the head of any department is mostly an administrator. The head of PsyOps may be a big title, but in reality that person would mostly work on budget, resources, project planning. The same way in an hospital, the main administrator do not operate on patient, surgeons working for that person do.
7) your protagonist is passive in your logline. She discovers that her vengeful husband has planted a virus to destroy. What does she do? Does she go home and make a cup of tea? You need to tell us what she is doing to solve the problem.
8) there is no tension, because what's the worst an electronic virus can do? Delete my file? Big deal, I've got everything backed up on the cloud. What is at risk needs to be more fleshed out.
I am reposting my previous attempt.
Locked in a nuclear submarine with the crew she was sent to evaluate, a shrink must win a deadly game of psychological warfare in order to stop the self destruct sequence initiated by a vengeful husband.
