Battleships: a ridiculous but awesome idea
This is not exactly convincing. Battleships, far from being a ridiculous idea, were a logical and necessary step for any navy wishing to project power at sea. They were so heavily armoured and gunned that for a long time, from the late 19th Century to just before WWII, the only realistic defence against a battleship was another battleship.While the Battle of Jutland may seem silly, the alternative would have been a bunch of smaller ships duking it out (probably for a similar result) or only one side possessing battleships and annihilating the other side.Manoeuvre warfare with a lighter fleet was not an option, as smaller vessels had smaller guns that frequently could not even penetrate a battleship's armour. So a battleship would've been able to pick off opponents at ease while they struggled to cause any damage. It's no good getting inside your opponent's OODA loop if you can't cause any damage.And the technology that would have permitted another nation to bypass the idea of a battleship altogether and attack it from a different angle just did not exist at the time. It was only decades after Jutland that naval aircraft and aircraft carriers became fast and advanced enough to make the aerial bombing and torpedoing of enemy vessels a real possibility. These days missiles are the great equalisers.Manoeuvre warfare is fantastically effective when the circumstances allow for it, but the available conditions, technology and personnel can sometimes make it ineffective. For instance, the German Blitzkrieg was extraordinarily effective against the static French defences in 1940, but the same forces and tactics came unstuck in 1941 when faced with a vicious winter and the Russian scorched earth style of defence.With reference to the hacker context, the lesson is that simply moving quickly isn't enough. You also need to understand what a competitor's real weaknesses are as well as understand which parts of their strengths you're incapable of attacking. If your enemy has battleships and all you have are frigates, then maybe you shouldn't be fighting them at sea.
