This is a pin, possibly of a torpedo, from Lockheed Martin in the United States. It features the LM and gold logo. While the details are unclear, it appears to depict something resembling a torpedo or missile. It was obtained in the United States and is a rare item not available in Japan. There is some rust on the fastener. Otherwise, it is in good condition. It is approximately 2.5 x 1.5 cm. I am also selling many other pins. If you purchase multiple items, I can offer a small discount, so please feel free to inquire.
