A Winter 2025 NEJ paper argues that early ship design often loses requirements traceability in the first 10% of the process due to document-driven workflows and rising system complexity. It proposes a “meet-in-the-middle” approach that blends naval architecture practice with systems engineering rigor, with MBSE as the authoritative digital source of truth.

A Winter 2025 NEJ paper evaluates whether water mist injection inside a gas turbine exhaust duct can reduce plume temperature and improve IR signature management. Using two-phase CFD with two-way coupling, it shows how droplet dynamics and evaporation physics determine realistic cooling potential.

A Winter 2025 NEJ paper introduces a federated-learning “digital twin” approach to detect and localize cyber attacks in distributed DC ship power systems without centralizing raw controller data. It targets both false data injection and controller hijacking while using robust aggregation to handle real-world controller differences and untrusted participants.

A Winter 2025 NEJ paper shows how the Mark V catalytic burner’s operating temperature directly drives submarine cooling and power burden—and why even a 100°F drop could meaningfully cut waste heat. It evaluates a platinum monolithic catalyst as a potential path to cleaner air at lower temperatures, with practical handling and recycling benefits.

A new Winter 2025 NEJ technical paper explains why integrating directed-energy weapons alongside traditional missiles and guns fundamentally shifts ship self-defense from a range-based problem to a time-, environment-, and power-constrained decision challenge—and why smarter coordination and automation will be essential to make lasers truly operationally effective.
