[#1, #2, #4, #5, #6, #7, #9, #18, #19, #23, #26] Capital hardware and systems: hydrophone buoy array purchase (~$10M), initial auditory pod stockpile purchase (~$100M), aircraft purchases (~$240M), UAV purchase/modify (~$30M), training/simulation rigs (~$3M), initial emergency/evasion kits (~$600k), comms/jamming dev (~$5.5M), specialized weapons R&D initial hardware (~$30M), BSL lab fit-out (~$11M), contingency reserve seed (~$50M), and related equipment.

[#3, #11, #16, #17] Command/operations center buildout, storage facility buildout, offshore generator/platform build, and semi-permanent offshore platform construction estimates (command center $~8M; storage $~3M; generator/platform $5.5M; small-purpose platform $40M).

[#2, #15, #19] R&D and laboratory setup costs: auditory mine pod R&D/prototyping (~$6M), acoustic/marine bioacoustics research program (~$5.5M), and initial medical/research lab staff/equipment (~$3M).

[#14] Initial environmental impact assessments and mitigation planning ($250k–$2M range; midpoint used).

[#20] Annualized insurance/loss-reserve held against replacement of capital assets (~15% of total capital invested used as policy here).

[#4, #5, #12, #16, #17] Aircraft and UAV operational deployment (crew, fuel, maintenance), salvage logistics and moderate platform fuel/logistics; includes recurring salvage hires and long-range sortie costs.

[#8, #13, #21, #24] Ship rerouting compensation/covert subsidies, legal/PR retainers, settlements/hush payments reserve and public-relations operations to maintain controlled narratives.

[#2, #3] Annual replacement and replenishment of auditory mine pods (assumed moderate usage 50–200 pods/yr; mid-range estimate used).

[#23] Annual contribution to contingency/catastrophic response fund for large-scale attacks or cascade scenarios.

[#6] Salaries, benefits, hazard pay and training continuation for specialized airborne containment teams (team of ~40 specialists).

[#18] Ongoing R&D/testing for specialized kinetic/acoustic countermeasures and legal risk modeling.

[#25, #7] Routine consumables and logistic support (fuel for smaller craft, parts, medical supplies) plus annual inspection/replacement of emergency/evasion kits.

[#15, #22, #14] Ongoing acoustic R&D operations, environmental monitoring, and data processing/modeling (compute and staff).

[#11] Ongoing operations, utilities and maintenance for shore-based command/operations centers and storage facilities.

[#1] Annual maintenance and replacement for hydrophone buoys (biofouling, storms, battery replacement; ~15–25% of buoy capital assumed).

[#9] Operation of NAVWARN/AIS/NOTAM broadcasting infrastructure and covert jamming/suppression operations (servers, satellite slots, ops).

[#19] On-call medevac, shipboard life support, and medical/psychological support operations for staff and survivors.

[#10] Bandwidth for buoy uplinks, drone/aircraft satcom, and operations centers.

[#26] Running costs for secure disposal and hazardous-material handling for biological samples.

[#27] Ongoing covert training/exercise program with civilian shipping and port authorities.
