CBI Probe Into Use of Chinese Components in India’s Dhanush Howitzers

India : The Central Bureau of Investigation (CBI) has launched a probe against Delhi-based Sidh Sales Syndicate for allegedly supplying Chinese components that were falsely certified as German-made for India’s indigenously developed Dhanush howitzers. The case has raised serious concerns over quality assurance and integrity in the country’s defence supply chain.

According to the investigation, the firm supplied Wire Race Roller Bearings sourced from a Chinese company, Sino United Industries (Luyang) Ltd, while claiming they were manufactured by CRB Antriebstechnik of Germany. Forged documents and fake certificates were allegedly used to misrepresent the origin of the parts.

Tests conducted at the Gun Carriage Factory (GCF), Jabalpur, revealed dimensional deviations in the bearings, rendering them unsuitable for use in the Dhanush system. This discovery prompted the filing of a First Information Report (FIR), which not only names Sidh Sales Syndicate but also brings certain factory officials under scrutiny for approving the substandard supplies.

The probe has highlighted vulnerabilities in India’s defence procurement process. The Dhanush howitzer, often called the “desi Bofors,” is a critical artillery system designed to fire 155 mm NATO-standard ammunition and enhance the Indian Army’s firepower. Any compromise in its components poses a direct risk to operational reliability.

The financial details of the case trace back to 2013, when Sidh Sales Syndicate secured a contract worth over ₹35 lakh to supply the bearings. The value was later revised to approximately ₹53 lakh in 2014, with deliveries made in multiple batches that year.

Beyond the immediate issue, the scandal underscores broader challenges in ensuring transparency and accountability in defence manufacturing. With India pushing for self-reliance in defence production, such cases threaten to undermine confidence in indigenous systems if not addressed decisively.

The CBI investigation is ongoing, focusing on the supply chain, forged certifications, and the possible role of insiders. Strict action, including criminal charges and blacklisting of involved parties, is expected once the probe concludes.

This case serves as a reminder of the importance of stringent oversight in defence contracts, where even the smallest compromised component can impact the safety and effectiveness of vital weapon systems like the Dhanush.
