## Executive read

### BLUF

April launched an unmanned surface warship into public view and updated the IS commercial-UAS file: DARPA and Navy leadership christened ACTUV prototype *Sea Hunter* in Portland on 7 April, and mid-month specialist reporting documented IS expanding commercial/homemade drones from propaganda and surveillance toward fire-spotting and possible weapons delivery — a year after the Fallujah trunk strike.

### Key judgments

1. **[Assessment — high confidence]** Reuters 8 April (Phil Stewart) and DARPA 11 April: 7 April Portland christening of the 132-foot unarmed ACTUV demonstrator, dubbed Sea Hunter; Deputy Secretary Work present; transition from DARPA construction to joint open-water testing with ONR; possible Navy transition ~2018 pending tests.
2. **[Assessment — moderate confidence]** Marine Corps Times 17 April (David Larter line): CJTF-OIR first said it destroyed an IS drone on 17 March 2015 (Warren quotes restated); 2016 reporting now includes propaganda, surveillance, indirect-fire spotting, “possibly weapons delivery.”
3. **[Inference — moderate confidence]** A crewless 132-foot ASW trailer and a $100 Amazon quadcopter dropping a grenade (if confirmed later) are the same month’s autonomy problem at opposite ends of cost.

### Analytic labels

- **Fact** — verified reporting or primary record
- **Assessment** — analytic judgment
- **Inference** — reasoned but not directly observed
- **Uncertainty** — unresolved information gap

### Source grades

- **A1** — authoritative primary record / directly confirmed
- **B1–B2** — generally reliable and corroborated
- **C3** — useful but requires caution

## 01. Sea Hunter christened — ACTUV leaves the shed

*Event / publication dates: ceremony 7 April 2016; Reuters 8 April; DARPA 11 April*

**Verified record — [Fact — B1]** Reuters: U.S. military christened an experimental self-driving warship to hunt enemy submarines; 132-foot unarmed prototype; “naval equivalent of Google’s self-driving car”; cruise two or three months. DARPA: Director Arati Prabhakar christened “Sea Hunter”; Work and senior Navy present; Portland; formal transition to open-water testing with ONR; September 2014 MOA; tests to begin summer off California after checkout and move to San Diego; possible Navy transition 2018. Missions: submarine tracking and countermine. Fetched/indexed: https://www.reuters.com/article/technology/us-military-christens-self-driving-sea-hunter-warship-idUSKCN0X42I3/ ; https://www.darpa.mil/news/2016/christen-actuv-prototype

**Threat landscape.** Large USV autonomy is now a named hull. COLREGS compliance and weapons policy are the next Control Fabric fights (Work, in contemporaneous coverage, said any lethal decision would remain human).

**Intelligence assessment.** [Assessment — high confidence] Sea Hunter was christened 7 April as an unarmed ACTUV demonstrator. [Inference — moderate confidence] The China/Russia ASW rationale in Reuters is the strategic frame, not a test result. [Uncertainty] Builder yard details beyond Leidos/Christensen-Vigor lineage are encyclopedic — not added from later Wiki.

**Opportunity.** The DARPA christening transcript.

**LRRK relevance.** Sense-Move-Act / Lab / Campaign / Passport. First dated ACTUV hull in this archive.

**Confidence.** High on date, name, length class, unarmed status.

## 02. IS drone fleet — a year after Fallujah, the mission list grew

*Event / publication dates: Marine Corps Times 17 April 2016*

**Verified record — [Fact — B2]** Piece restates 17 March 2015 Warren quotes (already in this archive) and describes a year of commercial/homemade use: propaganda, surveillance, indirect-fire spotting, possibly weapons delivery. Out-of-the-box drones on Amazon under $100 with short range/battery limits. Popular Mechanics December claim of a Kurdish-downed explosive-laden IS drone is earlier reporting, not independently fetched here. Indexed: https://www.marinecorpstimes.com/news/your-marine-corps/2016/04/17/isis-is-expanding-the-reach-and-sophistication-of-its-drone-fleet/

**Threat landscape.** COTS Sense is becoming COTS Act in specialist judgment. That is still one step short of a dated 2016 drop-video primary in this fetch set.

**Intelligence assessment.** [Assessment — moderate confidence] The 2016 mission-list expansion is a specialist synthesis. [Uncertainty] “Possibly weapons delivery” is hedged in the piece itself.

**Opportunity.** A dated 2016 drop video with a day-month.

**LRRK relevance.** Campaign / Kestrel / Watch.

**Confidence.** Moderate on the trend; low on a specific April drop event.

## 03. Phantom 4 shipping into a registered NAS

*Event / publication dates: 15 March store date; April wider retail in some accounts*

**Verified record — [Fact — B1]** March launch Facts stand. Registration 368k owners is the identity layer those airframes enter. Carry-forward PR: https://www.prnewswire.com/news-releases/dji-launches-new-era-of-intelligent-flying-cameras-300228654.html

**Threat landscape.** Vision-avoidance Phantoms and unregistered remnants share the same airports.

**Intelligence assessment.** [Assessment — high confidence] Phantom 4 is in the market this month. [Uncertainty] April unit sales not fetched.

**Opportunity.** An FAA Phantom-4-specific incident.

**LRRK relevance.** Passport / Campaign.

**Confidence.** High on market presence.

## 04. Part 107 still not final — June’s file if it comes

*Event / publication dates: no April 2016 operations final fetched*

**Verified record — [Fact — A1]** NPRM continuity. No April final rule fetched.

**Threat landscape.** Commercial operators still on 333; Pathfinder still research.

**Intelligence assessment.** [Assessment — high confidence] Negative for an April final.

**Opportunity.** A DOT calendar.

**LRRK relevance.** Control Fabric / Watch.

**Confidence.** High on the negative.

## 05. REMUS / Knifefish — undersea continuity beside Sea Hunter

*Event / publication dates: 2015 Hydroid contracts; July 2015 North Dakota*

**Verified record — [Fact — B1]** July 2015 Diplomat REMUS 600 sub-launch remains the last fetched sub-UUV primary. Sea Hunter is surface. Knifefish still LCS MCM without a 2016 fetched at-sea primary. Carry-forward: https://thediplomat.com/2015/07/confirmed-us-navy-launches-underwater-drone-from-sub/

**Threat landscape.** Three unmanned naval classes — UUV, USV, MCM UUV — are now all named in this archive.

**Intelligence assessment.** [Uncertainty] April 2016 UUV test hours not fetched.

**Opportunity.** An ONR April note.

**LRRK relevance.** Lab / Watch.

**Confidence.** High on continuity.

## Forward indicators

Ranked watchlist as of the collection cutoff (what a Watch desk would have monitored next).

1. Sea Hunter first open-water numbers (speed, seakeeping).
2. A day-dated IS munition-drop primary.
3. Part 107 final text.
4. Phantom 4 geofence vs P-56/airports.
5. Work’s “humans decide lethal” line in a written policy.

> **Collection integrity.** Reuters/DARPA Sea Hunter used (DARPA page timed out once; Reuters indexed). IS fleet piece is specialist B2 and does not invent a dated April drop. Part 107 June publication excluded. 2018 Sea Hunter-to-ONR transfer excluded.
