I'm wondering which dual launch of bigger warships I missed except
I mean wouldn't it be the biggest ever if two of Type 055 were dual launched now?
this is not to naysay China, not at all, just
If Something Sounds Too Good To Be True, It Isn't
Is that why you've always been asking for updates about the 055s at Dalian and whether they've been launched?
That is to say, you think it's "too good to be true" for two 055s to be launched at the same time?
If so, then I think you are looking at it the wrong way. Instead, you should be asking yourself when was the last time any shipyard in the world had built two destroyers in the same drydock at the same rate/stage before. The two 055s at Dalian were obviously built simultaneously -- we could see it when the first pictures of the 055 modules at Dalian emerged in 2016.
From there, it made sense to assume that the two 055s would likely be launched simultaneously since they were being built in the same drydock, at the same pace as each other.
Now, it may turn out for whatever reason like safety, that they may end up staggering the launches of the two 055s where both are floated but then one is launched into the fitting out pier and then the dock is drained and then the process is repeated for the second 055, but at this stage I don't think that seems like a likely way of doing it.
So for now, just sit back and relax. A dual launch of the two 055s is not a big deal nor should it be a surprise -- what should have been a surprise for you was the fact that they had gone about building two 055s in the same drydock at the same pace. After all that is what led us to where we are.
