Given the specifications that its designers are talking of, this ship is likely to be unaffordable in vast numbers, costing as much as the LCS. If you want to a capable workhorse, the SM-3 and Tomahawk may not be necessary. Something along the lines of Singapore’s Formidable class or South Korea’s KDX-II class ships should be adequate.
Still, trying to shoehorn SPY-1D(V) and strike lenght Mk-41 cells into a 3500 tonne ship will be interesting, to say the least.
