An open record of
Indian defence systems
and what moves through its seas.
simha is two things in one place: a sourced, community-maintained encyclopedia of India's land, air, naval, missile, space and C4ISR systems — and a live situational-awareness map of the Indian Ocean Region.
Six domains, one schema
Land
Tanks, artillery, small arms, ground systems
Air
Fighters, transports, helicopters, UAS
Naval
Carriers, submarines, surface combatants
Missiles
SAMs, cruise, ballistic, hypersonic
Space
Military satellites, counter-space
C4ISR
Radars, EW, sonars, comms
What we're trying to solve
Reliable information on Indian systems is scattered, unsourced, and quick to go stale. simha pulls it into one structured, citeable, correctable place.
An open systems encyclopedia
A structured, sourced database of Indian defence systems — every spec carries its citation, every entry its edit history. Built to be corrected by the people who know the detail.
Live IOR situational awareness
Aviation (NOTAM) and maritime (NOTMAR) hazards across the Indian Ocean Region on one map — launch splash zones, missile corridors and firing areas, refreshed automatically.
Community-maintained
Anyone can submit a draft. Edits flow through a revision queue, get reviewed, and become history. No black box — the whole record is open.
Want to help build it?
simha is community-maintained. If you know the systems, you can add and correct entries — every edit is reviewed and kept in the record. More ways to follow and contribute are landing soon.
