I was reading a Scientific America from the early WW1 days, and it though Zeppelins with "Aerial Torpedoes" could sink capital ships. While we know precision guided bombs are beyond the 1910's technology, what would have happened if the Kaiser had approved a R&D program in 1910 for such weapons with the following limitations:
1) Ten million marks lifetime funding.
2) Weight limit on weapons - 2000 lbs. Each Zeppelin carries two of them.
3) At least initially, the developers will focus on guiding by wireless communication.
4) The intended launch height of the weapon is 5000 feet at a rage of a 5 miles from the target.
The easy answer is the weapon would never even reach the prototype stage, but I will give my guess. A custom designed glide bomb that can penetrate the armor of a dreadnought is developed. With great difficulty, they get the electric motors working and the wireless communication to work some of the time, but the weapon is much harder to steer than expected. The problem that will doom the weapon as an effective weapon system is that even if the steering works perfectly, there is no way to accurately tell if the weapon is on target from 5 miles away. The weapon will be used in combat, but will never come closer than 100 meters to an actual enemy warship.
