C-Worker 4
L3Harris ASVThe C-Worker 4 is a compact unmanned surface vehicle (USV) manufactured by L3Harris Technologies (formerly ASV Global, absorbed via L3 Technologies merger with Harris Corporation in 2019). It is a 4.2m aluminium-hulled diesel-powered USV designed for coastal and offshore survey missions (hydrographic, oceanographic, environmental), capable of up to 48 hours endurance at 3.5 knots cruising speed and operable in up to sea state 4. It supports both direct remote control and optional autonomous waypoint-following with collision avoidance, and has been deployed by academic institutions such as the University of Plymouth. Several extracted facts relate to L3Harris corporate activities (VC-25B, VAMPIRE, radios) that are irrelevant to the C-Worker 4 system itself and have been excluded from reconciled facts.

Evidence-graded claims from the L3Harris ASV deep report
The Seasats X3/Lightfish micro-ASV completed a 2,500-mile autonomous transit from San Diego to Pearl Harbor in ~10 weeks (June 2024).
Marine Technology News [9] independently reported the same milestone event also announced in L3Harris's own press release [12], providing corroboration beyond vendor PR — though the degree of human supervision during the transit remains uncharacterized.
from L3Harris ASV deep report →L3Harris ASVs are operationally deployed with U.S. Navy Task Force 59 and have been delivered to the UK Royal Navy/DSTL.
Ocean News [13] independently reported the UK DSTL delivery, and multiple commerce and news sources [5][6][9] corroborate TF 59 deployment — though operational tempo, mission outcomes, and the precise level of autonomy used in live missions are not independently characterized.
from L3Harris ASV deep report →
ASView has accumulated 2,100+ hours at sea without human intervention across operational deployments.
This figure appears exclusively in L3Harris vendor sources [7][8]; no independent third-party test, customer statement, or regulator report in the dossier corroborates the specific hour count or confirms the absence of human supervision during those hours.
from L3Harris ASV deep report →ASView is COLREGS-compliant and provides fully autonomous collision avoidance without human intervention.
COLREGS compliance is stated consistently across official L3Harris product pages [8] and commerce sources, but no independent regulatory body, naval authority, or third-party test report in the dossier has certified or validated this compliance claim.
from L3Harris ASV deep report →The Seasats X3/Lightfish micro-ASV can operate autonomously for up to six months on solar power in all maritime environments.
Marine Technology News [9] and BusinessWire [11] both report the six-month endurance figure, but both are relaying vendor/investor claims rather than results from an independent endurance trial; the 2,500-mile transit (~10 weeks) is the only independently corroborated extended-endurance data point.
from L3Harris ASV deep report →L3Harris and BigBear.ai have integrated computer vision AI for vessel identification, classification, and pattern-of-life detection on ASVs.
The teaming agreement (May 2023) is confirmed by both BigBear.ai's own press release [10] and L3Harris sources, but the dossier contains no independent evidence that the integrated AI capability has been tested, validated, or operationally fielded beyond the partnership announcement.
