The Indian Coast Guard inducted its first domestically built air cushion vessel on 18 June 2026 at a Goan port. Now official registers with the defense ministry confirm this physical delivery occurred at the So, shipyard building. It features over 50% domestic parts.
The local registers show the key procurement deal anchors domestic defense manufacturing firmly within the private marine industrial sector of the country. And private Goan manufacturers secured the ₹387.4 crore contract to construct six identical amphibious units over the next 18 months. They firmly rejected foreign imports.
What Are the Immediate Consequences?
This delivery triggers immediate operational changes in maritime security and domestic industrial output across vulnerable coastal zones on the eastern coast. So the regional defense architecture adapts to new tactical capabilities near exposed international borders. Now the fleet expands.
Historically, the national navy imported expensive hulls from international suppliers at high economic premiums for coastal security operations. But this new domestic procurement model guarantees complete technology absorption through skilled Goan labor at local facilities. Records filed with the bureau prove local sourcing reduces acquisition costs by exactly 15% overall compared to import lines.
Previously, overseas shipyards dictated active maintenance timelines and essential spare parts availability to domestic operators during crises. Now this domestic contract secures a vital five-year post-delivery servicing agreement with Goan shipwrights at the Rassaim facility. This secures long-term operational readiness.
These new operational shifts compare directly with past maritime practices of importing foreign vessels from international builders. And they reveal a complete, sweeping overhaul of the state procurement model.
Domestic sourcing cuts acquisition costs by 15% overall compared to foreign imports.
Local service deals secure a five-year maintenance agreement at the Rassaim facility.
High domestic content reaches over 50% to secure fragile border zones.
Why Does the H-561 Deploy to the Sunderbans?
The vessel deploys directly to Haldia station to overcome severe limits of conventional steel patrol boats in shallow deltas. And the hovercraft flies seamlessly over shallow mudflats, sandbanks, and razor-sharp silt beds in the West Bengal delta. In contrast, conventional hulls run aground.
This deltaic region remains a major transit zone for illegal fishing and international smuggling networks near foreign borders. Yet standard inflatables sink or stick in the thick, knee-deep mangrove mud during extreme low tides. The versatile H-561 solves this.
How Did the Vessel Perform During Sea Trials?
The amphibious platform easily exceeded its contractual speed limits during official marine testing phases under heavy weather. So it clocked 52 knots during sea trials against a baseline requirement of exactly 48 knots under heavy weather. It carries eight tonnes easily.
This platform runs continuously for nine hours without needing any complex refueling operations during active border security patrols. And it transports up to 42 fully equipped personnel directly into isolated disaster zones during heavy monsoon storm seasons. Now rigorous testing confirms performance.
Who Controls the National Procurement?
The Ministry of Defence managed the contracting process alongside Goan shipbuilders to deliver the platform on schedule. But Chowgule Shipyards completed the physical construction of the vessel at their Goan facilities under licensing deals. Assistant Manager Gaurish Parab verified the physical success of the local workforce during extensive open water trials off the coast.
"The platform has already demonstrated performance beyond its design specifications, clocking 52 knots during sea trials," Parab stated. And a senior Coast Guard official noted that this vessel represents a fresh achievement for the local navy. He confirmed they fully absorbed technology.
