Shares of indigenous aerospace and defence manufacturer Sigma Advanced Systems Limited hit their 5% upper circuit limit after bagging an international contract valued at USD 102.23 million (approximately ₹973 crore) from a NATO alliance customer. The landmark deal underscores the accelerating appetite for Indian-manufactured precision military hardware across Western defence corridors. The news triggered heavy buying on the bourses, pushing the counter to an intraday high of ₹862.20 per share on the National Stock Exchange (NSE).

Scope of the Deal: Powering 155mm Artillery Systems

Under the terms of the agreement, Sigma Advanced Systems will manufacture and supply high-performance Base Bleed (BB) Units tailored specifically for 155 mm artillery ammunition shells.

• Execution Timeline: The contract carries a delivery window of 12 months, providing strong short-term top-line revenue visibility.

• What are Base Bleed Units? Installed at the rear base of long-range 155mm artillery shells, base bleed units emit controlled combustion gases during projectile flight to fill the aerodynamic vacuum behind the shell. This significantly reduces aerodynamic drag, extending the effective firing range of heavy artillery by several kilometers.

• Value Chain Expansion: Having already established capabilities in 155mm artillery shell bodies and electronic fuzes, adding in-house base bleed unit manufacturing positions the company as a full-spectrum artillery ammunition subsystems provider.

Phenomenal Multibagger Returns on Dalal Street

The latest NATO contract builds upon an extended bullish run for the stock, cementing its reputation as one of the standout multibaggers in the capital goods and aerospace segment:

• 6-Month Surge: The stock has rallied over 247% across the preceding six-month period.

• 1-Year & 3-Year Trajectory: Shares are up nearly 364% over the past twelve months and have rewarded long-term shareholders with a cumulative 1,807% return across three years.

• Long-Horizon Multiplier: Across a five-year holding window, the counter has logged an extraordinary 4,685% capital appreciation.

Expanding Footprint in Global Supply Chains

The ₹973 crore win is not an isolated export milestone; it closely follows an earlier ₹1,013 crore export order secured by the firm for 147,000 base bleed artillery shells. Sigma Advanced Systems currently derives roughly 80% to 85% of its overall revenue stream from international export markets, highlighting deep integration into overseas defence procurement frameworks. By consolidating the localized production of shells, precision fuzes, and specialized range-extension units, the firm continues to capitalize on global supply shortages in standardized 155mm munitions.
