Tachyon Detection Grid (Tachyon Net)
Federation-wide detection system that emits active tachyon beams to form an invisible grid capable of identifying cloaked Romulan vessels. The system operates as a fleet-spanning network where participating ships synchronize their tachyon emissions to create a detection web.
Deployment and Activation:
- Proposed by Captain Picard in the observation lounge, gaining approval from Shanthi (likely a Federation official or Starfleet representative).
- Activated on the Enterprise bridge via Excalibur feed, with Geordi La Forge warning that Romulans would quickly detect the field's presence.
- Successfully illuminates five hidden Romulan warbirds as glowing signatures upon activation.
Romulan Countermeasures and Adaptations:
- Romulans (including Sela) study the grid's pulse vulnerability but avoid direct engagement with the detection field.
- Later, Sutherland's torpedoes trigger similar tachyon flares, exposing an additional three Romulan ships.
Technical Nuances:
- Data analyzes sensor readings of the grid, noting that Romulans disrupted the network to evade detection by scattering ionized particle traces.
- Despite tachyon saturation, residual ionized traces linger around cloaked warbirds, allowing Data to reconfigure sensors to isolate these signatures.
Visual Representation:
- Displayed as a schematic on the Romulan Warbird command center monitor, showing Federation fleet positions and gaps (e.g., the Sutherland's warp failure).
- Sela uses the schematic to identify Picard's trap and redirect targeting to Data's ship instead.

Purpose
Detect cloaked Romulan vessels by emitting active tachyon beams between ships in the blockade fleet
Significance
Exposes Romulan covert aid to Duras sisters in Klingon Civil War, validates Picard's blockade strategy, forces Sela's countermove, and escalates Federation-Romulan brinkmanship toward direct clash
