Re: Most Powerful Military Powers in Star Trek
Well at demonstrated in Paradise Lost, the Excelsiors were refitted with modern equipment to make them comparable to modern ships in battle. No reason the Mirandas weren't either. Though I just always thought that the Federation using old Mirandas and what not was just them putting every hull they could into space because they needed them. It's common practice for navies these days to keep a reserve fleet of older classes in storage in case they need to rapidly expand their navy if a war breaks out.
