From mould bases to 155mm artillery shells — India's boldest SME defence pivot
₹30 Cr revenue, debt-free, 17% PAT margins — now manufacturing NATO-standard 155mm M107 shells with a US subsidiary and acquisition already done.
The business
Sunita Tools is India's largest mould base manufacturer by volume, now pivoting into 155mm M107 artillery shell manufacturing for defence. Four verticals — mould bases, sheet metal, die casting & machine parts — serving auto, pharma, FMCG & aerospace. Recently launched Sunita Defence Inc (USA) in Chicago and acquired 51% of New Mold Innovations LLC in Kentucky for USD 419K — a specialty grease manufacturer with 47 lakh cartridges/year capacity.
Why this business matters
India's defence production boom — ₹1.46 lakh Cr defence production in FY25, 92% contracts awarded to Indian firms. 155mm ammunition is critical
Global 155mm shell shortage — $6.8 billion global ammunition market growing at 8% CAGR. Post-Ukraine conflict, NATO nations face acute shell shortages
Make in India for defence — 68% of defence budget earmarked for domestic procurement. Sunita has LOIs till FY28 with 30% advance payment terms
The moat
Reality check
Defence approvals are slow & uncertain — shell manufacturing requires DGQA/OFB/MoD clearances. Revenue projections assume approvals that aren't yet confirmed
Negative operating cash flow in FY25 — ₹18.45 Cr locked in inventory (62% of revenue) for shell manufacturing ramp-up
Promoter family concentration — Pandey family holds ~65% and occupies all key management roles. Related party transactions of ₹20 Cr approved
Unproven at scale in defence — transitioning from ₹30 Cr precision tools to ₹200+ Cr defence manufacturing requires massive execution
Exit Trigger
Exit if 155mm shell manufacturing doesn't generate revenue by H2 FY26, or if defence order book doesn't reach ₹50 Cr by FY27
The verdict
One of the boldest SME pivots in Indian markets — from mould bases to NATO-standard artillery shells with a US subsidiary. The optionality is massive if defence execution clicks, but this is early-stage and unproven at scale.
Watch For
First 155mm shell revenue recognition (H2 FY26), DGQA approval status, US subsidiary order wins, FY26 full-year revenue, and inventory normalization.
