I want to know the answer to the following question:
What was lighter than the water-cooled pom-pom?
All the background I'm provided with is that "The air-cooled Bofors was vastly superior for land use, being much lighter than the water-cooled pom-pom, and UK production of the Bofors 40 mm was licensed.". Is that enough to answer the question?
Answer: yes
