Of course, that’s not surprising since this is their first major project. However, there are very few nations which provide ‘complete’ defense solutions nowadays. A lot of major nations (Germany, UK, Spain, South Korea, India, Japan to name a few) source design assistance, engines/machinery, sensors or weaponry for their warships from overseas.
Our own USN could learn a lot from these designs, but the NIH [not invented here] mindset has complete and unfettered control over NavSea and USN planning. The current LCS [Littoral Combat Ship] fiasco is merely the tip of this institutional iceberg in the USN and DoD.
