Originally the war ministry didn't want the spitfire but the designer knew his plane would make a difference and used his own money and private backers and a small government grant to continue developing the plane. The Soviet military turned down the t34 but thy guy built it himself bts by day his 34 by night. The US navy didn't believe in carriers most of the old salts felt they were a waste of money and more battleships were needed. What would have happened if none of those things never were. What if there never was a wasp or Yorktown class, Saratoga or Lexington. We won the war with carriers, but what if the admirals had gotten their way and we had built more battleships and no carriers. Would we be speaking German or Japanese.
