Trying to verify this. So far I found this but have not confirmed it's legit in any way:

Edit 3: USS Langley (CV-1) | World War II

On the entry of the US into World War II, Langley was anchored off Cavite, Philippines.[5][19] On 8 December, following the invasion of the Philippines by Japan, she departed Cavite for Balikpapan in the Dutch East Indies. In the natural state of alarm (the attack on Pearl Harbor had happened the day before) 300 rounds were shot at an object in the sky before it was realized that it was the planet Venus.[20]

Edit 4: This detailed history of the ship does not mention anything about firing at Venus:
