Streamlined Hull

A Streamlined Hull is a kind of ship structure, fuselage, chassis, or hull.

• Such hulls are typically designed to minimize atmospheric drag and maximize lift.
• It is a kind of Ship Equipment and a kind of Hull.

Description (Specifications)

A Streamlined Hull is a relatively compact hull crafted to support maneuver in atmospheres. It is a very common hull type designed for efficient atmospheric operation in addition to space travel.

Streamlined Hulls are very useful for atmospheric flight and wilderness refueling, but... They are widely considered wasteful of internal space usage. Some naval architects have estimated that nearly 20% of a streamlined hull's space is typically wasted. A dedicated spaceflight hull is most often far more space efficient.

CBPUSAL Function Designation Streamlining Spectrum

The Imperial Ship Builders Association (ISBA) qualifies modern naval hulls across this spectrum:

1. C. Cluster. An accumulation of compartments.
2. B. Braced Cluster. Structured for higher acceleration.
3. P. Planetoid. A hollowed nickel-iron asteroid.
4. U. Unstreamlined. Protrusions increase drag.
5. S. Streamlined. Cowlings and fairings decrease drag.
6. A. Airframe. Winged for performance in atmosphere.
7. L. Lifting Body. Radically streamlined lifting-surfaces.

History & Background (Dossier)

Before the advent of gravitic control technology, all aircraft were designed around aerodynamic, streamlined airframes. Spaceplanes, designed for performance in an atmosphere and the vacuum, kept to the same conventions. Spacecraft had little to no need for streamlining, in fact, since it represented extra cost, many dedicated spacecraft use no streamlining.

However, wilderness refueling involves diving into a gas giant so many ships use partial or full streamlining despite mission profiles that never involve atmospheric entry.

Despite the many advantages of dedicated spaceflight hulls, the ISBA estimates that most craft built within Imperial Space use streamlined or partially streamlined hulls. The increased efficacy of wilderness refueling and atmospheric flight with a streamlined hull are simply too tempting.
