Survey Vessel Large / INS Sanshodhak: India contract and delivery record — 21 Jun 2026

Development and reported outcome

On June 21, 2026, the Indian Navy commissioned INS Sanshodhak after the survey vessel had previously been delivered with an AUV as part of its hydrographic equipment suite. Commissioning brought the AUV-equipped host platform into Navy service for deep-water survey and collection of maritime, oceanographic, and geophysical data. The milestone is distinct from the March delivery and does not prove a separate AUV acceptance date, model, quantity, or operational deployment.[S1] [S2]

Contract, value and shipment signals

Delivery schedule, procurement window or milestone status: Host vessel delivered Mar. 30 and commissioned Jun. 21, 2026. Recorded contractual start: 2018-10-30 host-vessel contract.[S1] [S2]

Source verification and interpretation limits

UXV Searcher master source-coverage note: The June commissioning is a distinct host-platform lifecycle milestone from the March delivery, so it is retained. PIB separately confirms the AUV equipment fit.

Interpretation boundary: The source-specific record should be used to distinguish award, arrival, commissioning and completed delivery; these stages are not interchangeable.[S1] [S2]

UXV Searcher analysis — what the development changes

UXV Searcher interpretation — contract / recorded award outcome: The India UUV record for Survey Vessel Large / INS Sanshodhak is best treated as a committed commercial activity signal. The recorded award or contract is a stronger transaction signal than a tender; the amount and quantity still need separation into platforms, accessories, support and services.

Traceability for buyers: The dataset associates Garden Reach Shipbuilders & Engineers Ltd with Indian Navy for INS Sanshodhak embarked Autonomous Underwater Vehicle. This supports stakeholder mapping; supply-chain tier, exclusivity and signed-customer relationships need the underlying source before firm classification.

Client-use interpretation: For intelligence users tracking Hydrographic / Bathymetric Reconnaissance / Oceanographic Intelligence Support, the relevant next proof points are hydrographic survey performance and hydrographic-data outputs. Watch for acceptance or delivery reports, contract modifications and whether the stated amount covers equipment or ancillary work.[S1] [S2]

Quantitative evidence, calculations and limits

Quantification limit: No sufficiently attributed contract value or physical platform count is disclosed for this record. UXV Searcher leaves these fields unavailable rather than treating non-disclosure as zero or applying an unsupported market average.

The useful output is a qualitative stage and stakeholder signal, not a numerical forecast.[S1] [S2]
