@FalconSlayers @randombully can we also send our survey ships in south xhina sea as cooperative mission with vietnam, philipines and other south east asian countries. lets do the aankh dikhana which rajnath ji says

November 27–30, 2020
During a virtual meeting between Indian Defence Minister Rajnath Singh and his Vietnamese counterpart Ngô Xuân Lịch, the two nations signed an Implementation Agreement (IA) on Hydrography.
This agreement allows the Indian National Hydrographic Office and Vietnam Hydrographic Office to share hydrographic data and collaborate on navigational chart production .

Historical Survey Missions
Vietnam has actively participated in joint hydrographic expeditions in the SCS, particularly in the early 2000s:
In June 2000, a joint survey by Vietnam and the Philippines onboard R/V Biển Đông covered routes including Nha Trang to Manila, venturing into the Spratly Islands .
In March 2005, another joint expedition (JOMSRE‑SCS‑3) using the Philippine ship BRP Hydrographer Presbitero mapped parts of the Spratlys under a continued Vietnam–Philippines collaboration .
Again in April–May 2007, Vietnam and the Philippines conducted JOMSRE‑SCS‑4, surveying the Spratlys aboard the same vessel .

Vietnam’s Own Hydrographic Vessel
The HSV‑6613 “Professor–Academician Trần Đại Nghĩa” was built from 2008–2010, and is Vietnam's first modern ocean-survey vessel .
It is outfitted for extended hydrographic missions — with 5,000 nautical mile range and 60-day deployments .
However, there's no public data confirming that this ship has since conducted independent surveys in the contested South China Sea.

May 7–8, 2024
At the first Joint Working Group on Hydrographic Cooperation meeting, held in Ha Long Bay, India and Vietnam further deepened their commitment:
They signed an MoU establishing a Joint Working Group
Launched a training program for Vietnamese hydrographic officers in India
Agreed on the deployment of joint survey ships .

India–Vietnam Hydrographic Collaboration
June 2025: India’s hydrography ship INS Darshak visited Ho Chi Minh City to reinforce cooperation under the MAHASAGAR initiative . The visit included technical demonstrations and exchanges with Vietnamese officials.
Quad Maritime Domain Awareness (MDA) Systems
The Quad routinely collaborates on sharing maritime patrol aircraft data, satellites, UAV feeds, and undersea sensors through mechanisms like COMCASA-enabled Link‑16, Information Fusion Centre‑IOR, and P‑8/MH‑60R missions .
the shared sonobuoys, seabed sensors, and hydrophone networks actively collect and fuse oceanographic, depth, and acoustic data—exactly the kind of bathymetric and environmental intelligence submarines rely on.
Quad Initiative Data Shared Relevant Use
Sonobuoys (India–US) Oceanographic + acoustic Submarine tracking, bathymetry
SOSUS‑style seabed sensors (India–Japan‑US) Seafloor acoustics Wide-area submarine detection
India–Australia tow‑array hydrophones Passive acoustic surveillance Basin-wide UDA
COMCASA Link‑16 info exchange Maritime sensor fusion Domain & subsurface awareness.
This should be more than enough info.
Our current SSBN's don't have icbm range missiles
