It's not really alike because in the 1860s gun technology was lagging so far behind armor that a gunnery duel between ironclads could be inconclusive, so ramming was a legitimate tactic as was proven at the Battle of Lissa and the accidental collision that sank HMS Victoria showed that ram bows were still capable of sinking battleships in the 1890s.
What's happening now is more like if President Kennedy had said the US Navy needed to build new ram ships.
