Packet Ship: A Packet Ship primarily carries passengers on unscheduled routes.

• In that regards Packets are similar to Tramp Liners, except packets concentrate on unscheduled communications missions, while tramps concentrate on unscheduled trade missions.
• Packet Ships were once much more common across Charted Space before the rise of the X-Boat and related communications networks.
• The Supraclass designation is also known as Ship Mission, Ship Mission Code, Mission, or Ship Hull Designation.
• It is a starship supraclass.

Description (Specifications)

Packet Ships conduct similar missions to liners and courier vessels. They are generally understood to perform unscheduled missions where postal routes do not exist. Most are equipped with mail vaults and secure staterooms.

• Vessels such as Armed Packet (UF-CA33) perform unscheduled passenger service for those in a hurry. The crew can be trusted, but these little ships can still find themselves jumping into harm's way.
• Generally, packet trade is any regularly scheduled cargo, passenger, and X-mail trade conducted by space or starship. The ships are sometimes called "packet boats"—in the same manner as IISS communications craft are called "x-boats"—since their original function was to carry x-mail. However, in modern times they only supplement the official system. While "packet" can mean any small parcel, its usage here most likely comes from its meaning during the pre-spaceflight Terran Age of Sail, where it meant a parcel of important correspondence—usually governmental dispatches—or valuable items for urgent delivery.

General Definition

Packet ships are a class of small merchantmen generally in the 200 to 600-ton range designed to fill the gaps left by the trade lanes that follow the x-boat routes. They may be operated by planetary governments, private individuals, or corporations, they may even be assigned by a subsector duke concerned with developing the economy of their subsector.

• Their purpose is to carry x-mail, passengers, and high value cargo quickly from the trade hubs to the more distant worlds within a subsector, worlds often economically unreachable with less capable jump drives.
• A packet ship will typically be fully atmospheric capable, have a 2G to 3G drive for normal space operation and a Jump-3 or J-4 drive for FTL travel.
• In order to qualify for mail contracts and planetary subsidies, a frontier packet ship is routinely armed and is thus designated as an armed packet.
• Originally packet ships were often military surplus couriers or dispatch ships, either purchased or leased for civilian use. They have proven so useful for stimulating the frontier economy on the Imperial Fringe that purpose-built packets have all but replaced the older military designs.

Strategy & Tactics (Doctrine)

Packet ships perform high priority missions to deliver very high value cargo or passengers to sensitive destinations. They generally focus on high value passengers who carry top secret messages in areas where the fear of electronic intercept is a concern. Packet ships usually travel at high burn to make themselves difficult to intercept. Many use jump shadows or other masking features to minimize detection.

Supraclass Archetypal Roles

These vessels typically serve the following archetypal roles:

Selected Packet Ship Types
Archtype	Type Code/s	Exemplar	Remarks
Packet Ship	XU	''Excalibur'' class Express Packet Boat	The generic Packet Boat is represented by a variety of types with a variety of capabilities. X = eXchange U = commUnication
Armed Packet Ship	XUA	Xerxes class Armed Packet Ship	The Armed Packet Ship is designed to deal with frontier areas where hostile situations my be encountered such as a District, Rift Zone, or the Imperial Fringe. X = eXchange U = commUnication A = Armed, Gunned, Gunship, etc.
Packet Boat	XUB	No class-named example in database yet.	Packet Boat are officially system packet craft without jump drives. However, in practice, the term is used as a substitute for packet ships. So, many such Boats have jump drives despite the contradiction of terms. Such vessels can be smallcraft or bigcraft. They are system communicators in which a jump courier isn't warranted such as for extended mining or science operations in the Remote System, Far System, Oort Clouds, Kuiper Belt, Hill Sphere, or the like. Such operations save considerable amounts by not needing to invest in jump drives for scheduled, routine communications service. X = eXchange U = commUnication B = Boat (...no jump drive, limited to NAFAL propulsion, etc.)
Dispatch Ship	XUD	Chercheur class Fleet Dispatch Courier	Dispatch Ships focus on even smaller loads and fewer passengers than the typical packet ship. Dispatch ships often focus on VIP transport and sensitive high value cargos. X = eXchange U = commUnication D = Dispatch
Fast Packet Boat	XUF	Excalibur class Express Packet Boat	Express Packet Boats use more capable jump drives, often in the J:5-6 range. But, not always. Some express boats are named as such, but use regular frames and drives. These boats, especially the higher G models are known to be used as light, nimble blockade runners. X = eXchange U = commUnication F = Fast, Frontier, etc.
Packet Liner	XUR	No class-named example in database yet.	Packet Liner are much larger ships able to handle more VIP passengers. Packet liners are known to be used as heavy blockade runners. X = eXchange U = commUnication R = Liner, Blockade Runner, etc.
Vargr Packet Boat	XUV	''Dhaztuen'' class Packet Ship	The Vargr Extents is far more chaotic and dangerous than Imperial Space. Larger, better armed and armored hulls tend to be the norm in use by Vargrs. X = eXchange U = commUnication

History & Background (Dossier)

A number of types of communication vessels exist, and the packet ship has come to occupy a ship mission niche not occupied by x-boats, courier vessels, relay vessels, or other kinds of ships that perform communication duties. Packet ships were once far more numerous before the establishment of the X-boat System in the year 624.

They remain in use as of 1105, but are much less prevalent today. Some packet ships such as the Vargr ''Dhaztuen'' class Packet Ship or ''Dhaztuen'' class Far Merchant are also double-missioned in the same manner as Scout/Couriers.
