Something different this time around...

The Advanced Naval Vehicles Concepts Evaluation project or ANVCE was initiated to obtain the necessary information for naval vessels for the 1980-2000 time frame. One of the design studies during this period is the aforementioned Boeing hydrofoil HYD-7, an anti-submarine warfare orientated escort.

The design was to displace 1,300tons and be capable of 70 knot dash speeds whilst for its size be very heavily armed with:
  • 24x vertical launch Advanced Self Defence Missile (ASDM) (as yet undeveloped but seemingly likely to result in RAM or ESSM)
  • 8x vertical launch Harpoon
  • 12x rocket-propelled Advanced Lightweight Torpedoes (The weights suggest a Sea Lance sized weapon or Sea Lance itself)
  • 6x Mk.48 heavyweight torpedoes in fixed launchers

In addition to the plethora of weapon systems the design was also schemed with:
  • The launch and recovery of remotely piloted vehicles via a pneumatic ram and net. (12 in total)
  • Both rocket and over-the-side launching of sonobuoys (6+14)
  • Towed linear array sonar
  • Active/Passive towed sonar (SADTOS)
  • Active/Passive Reliable Acoustic Path Sonar (APRAPS)

Furthermore, the design was developed in such a way as to be able to undertake the mine-countermeasures and mine-laying missions with stern area being modified to suit.

Sensor wise the design centred around a developed higher-power TAS and lightweight TWS FCR with an infra-red detector mounted high on the mast for supplementary and emergency use.

It should be noted that the placement of some antennas is conjectural based on requirements outlined in the brief.

Very nice work, someone has been keeping their eyes on the recent spate of US hydrofoil projects over at Secretprojects. ;)

APRAPS is not an acronym I'd seen associated with that effort, so that'll be a useful google term in the future!

It's a nicely-drawn effort, although in common with a lot of paper sketches from that era, it seems stupendously overloaded with combat systems and electronics. Nearly as bad as some beginner Shipbucket drawings ;)
