Answer: United States
Notes: The Indian Navy deployed a P-8I maritime patrol aircraft to Guam to join the US-led Sea Dragon anti-submarine warfare (ASW) exercise 2026. The exercise includes QUAD partners: United States, India, Australia, Japan, and also New Zealand. Multiple P-8 aircraft participate, enabling better coordination due to similar systems, sensors, and data-link capabilities. The drill improves ASW skills by training crews from simulated targets to real submarine detection with 200+ flight hours. Joint classroom sessions are also conducted to refine tactics and coordination. The deployment comes as India ensures safe passage of merchant ships in the Arabian Sea for energy security.
