Was this explosion necessary?

I am all for the Navy doing its thing although not sure this test was required.

Probably not. But, what the heck, why not detonate it under the ship? Then they would know for sure.


Heck, there's always something that will take down this ship and one may not know what or when it's coming.... especially in war.

And your experience in certifying warships is?

People complain about military spending until we REALLY NEED it.

These types of tests are absolutely required. There are extremely sensitive electronics onboard that need to be tested for shock resistance. Part of my job is certifying the landing systems onboard CVNs (the SPN-41B and SPN-46). Explosions like these can absolutely knock these systems out of battery, which would mean no precision landing capability for the Air Wing. We need to know that the equipment meets design specifications before we can declare it operationally ready.

In my some what limited knowledge of commissioning 13 billion dollar warships I say it’s completely necessary. You are welcome to your opinion but my freedom is worth this expenditure.

I guess the question is what would they do if it failed?!?! Lmao. (Go build another one? Make it into a cruise ship). Try to raise it from the ocean bottom and have every engineer submit their resignation?

That being said, I am sure the tech/engineering weenies knew it would be fine.

I think this may have been a message to folks like Iran that says “you can get close in a small craft suicide bomb run, but we will light you up with chain guns and it will have no effect other than to turn Tehran into a parking lot.

Im all for it

That's a good point, but could we assume there's a LOT more testing way before it gets to this kind of explosion? And wouldn't there be back up systems also?

Gotta love TF, so many questions about simple trawlers but question how to go about testing warships.

Testing a piece of equipment on a lab bench is one thing - testing it installed on a ship is another. You would be surprised (and probably horrified) to see how some of these sensitive electronics are mounted to the structure of the ship. The final steps of testing any new system, or system of systems, is to test it as it would be installed and operated in its final form.

I'd rather not go into a discussion of specifics regarding back-up systems/redundancy, etc. This topic gets sensitive very quickly.

The purpose of the test was not to see whether the CVN would sink!

These shock tests are EXTREMELY expensive; so you can assume it is not something done willy nilly. Such tests are ONLY done on one ship, usually the lead ship, per class. It is NOT a structural survival test of the ship's hull because just think about it; are we really gonna take such a risk? Near misses by enemy action and explosions of tactical nuclear weapons are a part of the risks of naval warfare, and you want to be sure that short of a direct hit your stuff will continue to function in order to fight back. If all the electrical breakers trip just because of a nearby explosion, your ship could be "down" long enough for the enemy to take advantage of your helplessness as systems are brought back on line. You should see what the Army does to it's new armored vehicles! It blows them to heck in an effort to find the weak spots.

Maybe...

Blowing up and stress testing a vessel, that is designed to come under fire, to confirm its effectiveness makes sense to me. It's a few million dollars well spend ensuring lives will be saved.

$14,000 toiiet seats? Less so.

Ever here the full story on $14,000 dollar toilet seats?


I haven't heard them all but a few make perfect sense and sometimes the not so shameless government contractors manage to slip in a few over charges.


Kinda like a $5 part that is no longer OEM , now costs $99 with $50 shipping/handling charge from XYZ Marine website.

There are many reasons to do something. I believe it factored into the decision at a minimum, but what do I know? These tests are SOP but the Navy has commissioned several large ship recently without doing it.

Aside from the technical justifications (which i avoided in purpose since i have no qualification) this test also lets folks know our capabilities. (Which can be a deterrent)

Whats the purpose of publicizing it then? Everything is done for a a reason.

I do believe it is a first of class type of test.

Yes. I agree. I believe they did not do it for the newly designed littoral class ships. (There was some sort of controversy surrounding it something where they only used 10k worth and delayed it until after commissioning)

This is not the first time they've done it. One time, an earthquake was reported offshore of Daytona and it turned out to be the Navy testing one of these tests... I felt the vibration and the windows rattled like a NASA launch... and I was 80 miles from Daytona.

The littorals would crack up if they did that. They have never been able to traverse the panama canal without an incident... Great to have a ship so expensive that they had to cancel the ammunition because we can't afford it.

Never let government contractors tell you what they think you need.
