Evidence & current status
Current individual pages differ from older pages and from one catalogue-unit conversion. T24 current data: 27.5 ft/8.4 m, 7,500 lb/3,400 kg craft, 1,800 lb/816 kg payload; T18 figures shown in the main specification rows.
The Devil Ray T18 and T24 are distinct sizes within MARTAC's surface-vessel family. The T18 emphasises transportability, while the larger T24 provides additional deck and payload space and can support other uncrewed systems. Neither should inherit the dimensions or capacities of the existing T38 catalogue entry.
The current individual product pages are the baseline here. They differ from some older MARTAC pages: the T18 now lists a lower burst-speed headline, while the T24's current length is greater than older descriptions associated with its model number. The record therefore preserves current named-page values instead of treating the number in a model name as a physical dimension.
Both are offered with multiple control modes and communications options. MARTAC reports use by US and allied forces, but model-specific operator acceptance was not fully established in this review. That distinction is reflected in supplier-reported status. A complete delivered specification should identify the hull revision, engine choice, fuel load and installed payload rather than combining the highest advertised figures across the family.
