What significant contributions did the Seabees make during WWII?

The Seabees made extensive and vital contributions during World War II, and the correct answer highlights the breadth of their impact. Their construction efforts included building 111 airstrips, which were crucial for launching air operations and providing support for ground troops. The construction of 441 piers also played a significant role, allowing ships to dock and unload supplies, equipment, and personnel efficiently.

Additionally, the Seabees were responsible for constructing hospitals that had the capacity to treat 70,000 patients, which was vital for caring for wounded soldiers and providing necessary medical services. Building 2,558 ammunition points ensured that troops had the necessary supplies and resources for combat operations.

Together, these achievements underscored the versatility and expansion of the Seabees' role beyond just combat engineering, as they contributed significantly to the logistical and support infrastructure that was essential for the success of military operations during the war. Therefore, the option that encompasses both the construction of airstrips and piers, alongside the establishment of medical facilities and ammunition points, accurately reflects the comprehensive contributions of the Seabees during WWII.
