I am thinking of drawing inspiration from World War 2 warships for my space opera series. The space ships in my series will share the same name as many of these real-life vessels. This will be similar to how the USS Enterprise from Star Trek shared the same name with a real-life World War 2 warship. They will even share the same model names such as dreadnoughts, frigates, and corvettes. In addition, I will be drawing inspiration from fighter planes and firearms from the World War 2 era. Like the warships, they will share the same model name as the real-life weapons. However, the ones in my space opera series will be far more technologically advanced. Normally, World War 2 is not my preferred time period, but I found a gold mine of inspiration in terms of weapons, military ranks, ships, and battle tactics.
