They have had submarines around for many years.
- There are personal submarines, nuclear submarines and the type of submarine they use in aquatic tours, and even during WWI and Civil War.
The earliest submarine was first built in 1620. It parakeet under the River Thames. The Confederate Navy used a submarine during the Civil War. Working as an Heating and Air Conditioning worker in the Navy, I tested many of the submarines they now have, however I never knew when they started putting Heating and Air Conditioning plan in them. I was sure there was no AC in 1620, or they would have had it much earlier in homes. I also knew they wouldn’t have had Heating and Air Conditioning in the 1700, or 1820s, however they do now. Without Heating and Air Conditioning the women who lived in these submarines wouldn’t have been safe. They would spend weeks under the water, and without Heating and Air Conditioning for ventilation, heating and A/C, the air would become sick, and many people would have died. I was important in keeping these people safe while I was in the submarine and under the ocean for such long times. I became an Heating and Air Conditioning worker while I was in the Navy, and I enjoyed my job, however I couldn’t wait to finally because a normal citizen. I told my dad when I was ready to come home, and asked him if she had a position for me in her Heating and Air Conditioning business. It was difficult going from being a Naval officer on a submarine to being a official civilian, however I was still doing what I enjoyed. I was an Heating and Air Conditioning worker.
