Any host becomes
a drone strike node

A dense magazine of loitering munitions and kamikaze drones, salvo-launched from a host already in service — across ground, surface and subsea, under jamming and without GNSS.

Easy to integrate

One node, any host, your effector


Any loitering effector

Integrate the operator's own munition — the box stays the launch node. Or load ours: the Silentis FPV Strike UAS, stacked in the magazine, or the winged, tube-launched Silentis LR Strike UAS.

Any host

UGV, truck, 4×4, unmanned surface vessel or submersible — configured onto the host you already run.

Stand-off, no crew

A host plus the box is stand-off strike without putting a crew at risk: massed launch from well behind the forward line, a pattern already in the field.


Agnostic by design, tailored in practice: the smart core is a product, but every node is configured and qualified to your force — your host platforms, your chosen effectors, your interfaces. You field a launch node adapted to how you operate.

What the box does

The launcher, packaged around the smart core

  • Multi-cell magazine — folding drones packed dense, loaded like rounds.
  • Salvo launch — fired in ripple like a rocket-artillery system.
  • Launch-deconfliction interlocks — inhibits and fire-sequencing checked before release.
  • Autonomous safe-launch sequencing under electronic warfare.
  • Launch-grade navigation without GNSS — the accuracy a guided strike needs, held under active jamming and spoofing.
  • Operator-in-the-loop or autonomous launch, as your rules of engagement set; arm, safe, abort and wave-off retained when an operator is in the loop.
  • Encrypted, jam-resilient link — mesh networking between nodes and beyond-line-of-sight relay.
  • Fibre- or radio-linked launch — the box holds the effector's link from the launch point.
  • Cross-domain effector handoff between nodes.
  • Reload is a canister swap — each round ships sealed in its own canister; the tubes and the node stay, the effector is the consumable.
  • Configured for your open-architecture effector.
  • Carries tube-launched ISR drones as well as strike effectors — recon-strike from one magazine.

This is the reconnaissance-strike (recon-strike) layer buyers describe in their own dialects — tube-launched loitering munition, one-way effector, munition téléopérée, deep- and middle-strike, or simply kamikaze drone in open-source press coverage — carried on a distributed net of launcher nodes. The box is the tube-launch layer that puts a dense magazine of loitering effectors on a host already in service, dispersed and salvo-capable. Effectors are attritable and refreshed on short cycles, so the node is fielded in numbers and re-bought as the net is consumed — recurring capital.

Operator-guided strike

The operator chooses the moment, the angle and the aim point


An operator-guided loitering munition fired from Umbra Strike stays under control until impact, which is what separates it from a rocket that is committed the moment it fires.

Pick the approach

The operator selects the attack vector and the timing, coming in from the rear, the flank or in a vertical descent.

Hold, abort, retarget

The munition holds over the target area, and the operator can wave it off or retarget it up to the final dive, choosing the impact point for a surgical strike that limits collateral damage.

Crews out of the threat zone

An unmanned chain from launcher to target keeps operators out of the threat zone, and delivers fire on demand without moving a force forward.

From man-pack to subsea

Umbra emplaced at the site it protects
Fixed siteEmplaced at a base or firing position you hold — ready on cue, reloaded between missions.

Pre-positionedDeployed in advance for sustained operations — left unattended ahead of an advance or beside a route, sealed and dormant, its drones kept ready until cued.
Unmanned ground vehicle (UGV) strike node
Vehicle-mountedUnmanned ground vehicle (UGV), truck or 4×4 — mass that follows the force.

Configured onto a host you already run

Slots onto a host already in service


The node is built to bolt onto what you already run — no purpose-built platform, no clean-sheet integration. Fit it, power it, talk to it, and the host is a strike node.

Mounts on what you run

Standard ISO twist-lock fittings onto a deck, flatbed or hull — no host-build, no bespoke cradle.

Runs off host power

Vehicle DC or naval AC drawn straight from the platform — no host-side electrical modification.

Talks over an open bus

An open, documented data interface — no black-box OS, no bespoke host software to field.

Sovereign by construction — EU-made and ITAR-free, designed in the EU with no US-origin content. The smart core is open where it counts and proprietary only where the hard IP lives — see the architecture.

Cross-domain

Subsea is the seam few can reach


A pressure-tolerant node rides out weather submerged, then surfaces to launch — the highest-value variant and the hardest to build, where sealing, corrosion and fault-tolerance decide reliability. The same smart core carries across man-pack, ground, surface and subsea without a redesign, which is what makes cross-domain handoff between those nodes a single layered network. Ruggedness at volume is the second wall of the moat, and where the EU manufacturing base is strongest.

In the field today

Host-launched effectors are already deciding engagements


Events from today's wars — the strategic results a host-launched effector layer is already delivering, and the scale navies are now buying into. Umbra is the launch node that puts that pattern on any host.

Black Sea · Jan 2025 3 air-defence systems destroyed

Magura V5 unmanned boats launched FPVs that destroyed two Pantsir-S1 and an Osa — the first USV-launched strike on land air-defence; ≥4 warships sunk, the fleet "functionally inactive."

Kyiv Independent · Jan 2025
Ukraine · Mar 2026 11,000+ strike sorties a day

Launched drones now fly more than eleven thousand combat sorties daily — the tempo a launch layer must sustain.

RBC-Ukraine · Mar 2026
Taiwan · 2025 1,320 attack USVs contracted

Unmanned launch mass bought at scale — up to 1,600 planned. The host-launched effector is going global.

How a programme runs

From specification to operational capability


An Umbra Strike programme runs in four phases, with training running alongside integration so crews are ready when the system is.

01

Specify

The system specification is finalised from your operational requirements: hosts, effectors, interfaces and rules of engagement.

02

Integrate and qualify

System assembly, integration testing and operational acceptance trials, completed on your programme.

03

Field

Transport, site preparation and equipment staging at your operating location.

04

Train and reach capability

Training runs from ground instruction to tactical integration exercises: launcher type training and a munition-operator course, covering emergency procedures, radio datalinks and electronic warfare, and maintenance. Rollout is phased, starting with limited-range operations and expanding to the full mission envelope.

Standards

Built to the standards a programme checks for


Designed to the open interoperability standards a NATO or EU programme expects — STANAG 4586-compatible, MOSA-aligned (US 10 U.S.C. §4401), with ASTERIX, Cursor-on-Target and SAPIENT cue-in — and with a qualification path designed to the US and European defence standards (MIL-STD / NATO STANAG / AECTP) that clear a launcher to field. ITAR-free, EU-designed and EU-made. Silentis holds no certifications today; conformance is completed on your programme.
