Navis Mercantilis

Navis Mercantilis The Imperium of Man is the greatest galactic empire of its time, spanning from Ultima Macharia on the very edge of the western rim to the shrouded Eastern Fringe almost a hundred thousand light years away. Uniting its million worlds is perhaps the greatest weapon and resource available to Man: the Imperial Fleet, controlled by the powerful bureaucracy of the Adeptus Administratum. The Imperial fleet can be broken down into three primary components; the Navis Militares, protecting the Imperium with its great warships, the Navis Mercantilis, handling the flow of tithes and trade in the Imperium, and the Navis Civiles, whose ships are owned and controlled by noble lords, guild masters, free traders and other privileged citizens. Of these three fleets, the Navis Mercantilis (or merchant fleet) is by far the greatest. In most Imperial sectors, the merchant fleet will be ten times bigger than the military and civil fleets. The name of the Navis Mercantilis is actually somewhat misleading, as free trade makes up a relatively small portion of the traffic between Imperial worlds. The primary purpose of the merchant fleet is arguably the collection and distribution of tithes under direction of the Departmentos Conlatio and Auctus of the Adeptus Administratum. Due to the high degree of specialisation of Imperial colonies, there are many worlds that are utterly dependent on external supplies in order to be of use. Forgeworlds and industrial worlds are some of the most valuable types of Imperial colonies, but these would be almost worthless if not for a steady supply of food from agriworlds and ores from mining worlds. It is the function of the Navis Mercantilis to drive this circulation, in many ways acting as the blood of the great body that is the Imperium. While the flow of tithes is arbitrarily controlled by the Adeptus Administratum, the Navis Mercantilis also has an important second function from which it was originally given its name. Because ships with warp drives are so very expensive, trade would be all but impossible on many worlds if not for the services of the Navis Mercantilis. By providing a public transport service to sanctioned commercial organisations, the Navis Mercantilis is able to stimulate economical growth. Trade cartels that cannot afford building or purchasing their own ships may rent space onboard the vast merchant vessels of the Navis Mercantilis as they pass by on their scheduled routes. Many interstellar trade syndicates and cartels have started out by conducting business via the Navis Mercantilis, eventually gathering enough wealth over the centuries to purchase their own vessels in the Navis Civiles.

The Merchant fleet in battle Few vessels in the Navis Mercantilis are entirely defenceless. In a galaxy filled with hidden dangers, xenos raiders, renegade fleets, pirates and warp-spawned behemoths, even ore carracks and trading galleons are equipped with ranks upon ranks of weapons to deter attackers and deal with miscellaneous dangers such as asteroids or minefields.

Author’s note: Below, you will find rules for merchant vessels in BFG and a special BFG convoy scenario. The reason I have made additional rules for using transports in BFG is twofold. First, it’s a great excuse to convert and paint a whole bunch of new ships for a BFG fleet. Anyone can just slap together a new type of battlecruiser, but building a tugboat or sprint trader is a different kind of challenge. Second, while the trade convoy is one of my favourite scenarios for BFG, I find that it doesn’t really work on a grand scale. The nervous tension of trying to avoid discovery by a squadron of enemy escorts isn’t quite there when you’re cruising forward with two battleships on each flank. The rules below allow for greater battles involving bigger merchant vessels, allowing people [like me] to find a use for their newly converted super-heavy barge.

Against dedicated attackers, the ships of the Navis Mercantilis are extremely vulnerable and so must avoid enemy contacts at all costs. The ships of the Imperial Navy and Adeptus Astartes are ever vigilant, constantly patrolling and guarding Mercantilis trade routes to ensure the safety of unprotected merchant vessels. In regions threatened by war, all nonmilitary traffic is ceased immediately, so not to sacrifice the vulnerable and valuable Imperial merchant vessels. Some trade convoys however, must reach their destinations at regular intervals no matter what enemies lay in their way. From the heart of Segmentum Solar, enormous trade fleets fill their cavernous holds with vital cargo and set out to central locations around the Imperium, sailing along the major trade lanes with huge military escorts. To these Solar Merchant fleets, reports of xenos raiders and pirate ambushes are acknowledged with stoic determination, as billions of lives depend on the arrival of their precious cargo and future generations depend on their safe return back to the Segmentum Solar.

Caravel transport…………………… (transport capacity: 1) Caravels are represented by an ordnance marker and counts as ordnance to all intents and purposes. If a caravel marker comes in contact with enemy attack craft (fighters, bombers or assault boats), roll a D6 for each enemy attack craft in contact. If any of the attack craft score a 4 or higher, the caravel is destroyed and removed from play. Caravels may be attacked with long range weapons like other kinds of ordnance, using the normal rules. Caravels have a speed of 10 cm, allowing the ship to move 10 cm per ordnance phase (i.e. 20 cm per turn)

Merchant vessels: The ships of the Navis Mercantilis are generally not built with the same advanced technology as the Navis Militares, the Imperial Navy. In addition to their inferior defensive capabilities, Merchant vessels are often more sluggish, lacking the powerful engines used by the Imperial Navy, which makes them harder to manoeuvre and slower to accelerate. Naturally, the officers and crew of Merchant ships are rarely as skilled or experienced in dangerous situations as those of Navy ships and most sailors in the Navis Mercantilis may go their entire life without seeing anything like combat, in many regions of the Imperium. Merchant fleet ships using All Ahead Full orders only add +3D6 cm to their speed. They also reduce their randomly rolled Leadership by one, so they will have a Leadership value of between 5 and 8. Variants; There are many types of merchant ships in the Imperium beyond the categories based on volume and cargo capacity. Sprint traders, frontier traders, armed merchants, jump tenders, bulk traders, fuel carriers and void cruisers are the most common types of specialised merchant ships, though there are also more common variants including fuel carriers, ore carriers and passenger ships. The large convoys plying the major trade lanes of the Imperium will usually have a mixed composition of such ship types, depending on the needs and demands of the Adeptus Administratum, but occasionally strategic considerations will prompt a request for sprint traders or armed merchants specifically. Sprint traderSprint traders are a class of merchant ships with tremendous speed at the cost of cargo capacity. They are expensive vessels, with advanced engines that approach the capabilities of Imperial military vessels, and their services are available only to the richest and most privileged citizens and adepts. Sprint traders are used for a variety of purposes, but most commonly carrying luxury goods, important personnel, fresh food or valuable lifeforms. Sprint traders are also sometimes commandeered by Inquisitors travelling incognito and by smugglers or rogue traders looking to bypass Imperial or xenos blockades.

A clipper, freighter, galleon or carrack may be upgraded to a sprint trader at the cost of 5 points per each transport capacity point. (A freighter with transport capacity 2 must pay 10 points.) This gives the ship a +5 cm speed bonus and also provides a +4D6 cm speed bonus when using All Ahead Full order instead of +3D6 cm. Sprint traders have half the original transport capacity of their ship type. Armed merchantArmed merchants are simply merchant vessels that have been either constructed or refitted with military grade weaponry, the likes of which are usually reserved for the Imperial Navy. While most Imperial transports are equipped with a small battery of weapons to discourage pirates and raiders, they are easy prey in a real battle. Armed merchants are often sent to warzones or frontier worlds together with Imperial Navy escorts in situations where enemy raids are not only possible, but almost certain. Not all merchant ships are normally refitted in this way, however. The smallest caravels would be practically useless as transports if equipped with massive military grade weapons, and the largest vessels such as superheavy barges are so valuable that they usually have dedicated Imperial Navy escort squadrons instead. A clipper, freighter, galleon or carrack may be upgraded to an armed merchant at the cost of 5 points per each transport capacity point. (A freighter with transport capacity 2 must pay 10 points.) This gives the ship a 50% increase in weapon battery strength, with no additional range. For example, a freighter with strength 2 weapon batteries will have strength 3 weapon batteries if upgraded to an armed merchant ship. The upgrade is made to each battery (port, starboard and dorsal). Armed merchants have half the original transport capacity of their ship type.

Convoy battle In this scenario, an Imperial merchant convoy is en route to its destination, carrying enormous amounts of valuable cargo, when a large enemy fleet appears and begins to engage. While initially trying to avoid battle in order to protect its cargo, the Imperial convoy is eventually trapped and must defend itself. The attackers must destroy as many Imperial transports as possible before the battle is over.

Forces The Imperial convoy may have any number of transport ships, each with a different transport capacity. However, for every 100 points of military vessels (using the Imperial Navy, Adeptus Astartes, Rogue Trader or Adeptus Mechanicus lists), the convoy must have 1,5 transport capacity points. For example, in a game of 2000 points, the convoy must have 30 transport capacity points divided between its transports. These 30 points could be divided amongst fifteen freighters, three heavy barges or a variety of other selections. Any upgrades made to the transports count would be included in these 2000 points. The attacker has an equal amount of points as the defender, the Imperial convoy.

Battlezone The convoy may be attacked anywhere, even in orbit of its destination or point of departure. Often, convoys will be attacked in deep space, just as they emerge from the warp. Any method for placing celestial phenomena which can be mutually agreed upon by the players is acceptable.

SetSet-up The attacker must split his forces so that between 25% and 50% of his fleet (calculated in terms of point cost, not number of ships) belongs to attack group A and the rest belongs to attack group B. The attacker first deploys attack group B, then the Imperial convoy deploys and finally the attack deploys attack group A. Note that all ships in each deployment zone must face the same direction, as indicated in the deployment map. Attack group B and A may be deployed up to 30 cm from their short table edge, and the Imperial convoy may be deployed anywhere on the tabletop, but not within 30 cm of the enemy. The set-up represents attack group B chasing the convoy into the jaws of attack group A.

First turn Each player rolls a dice and the player with the higher score may choose whether to go first or second.

Special rules In this scenario, the attackers have successfully brought the Imperial convoy to battle. Some attacking ships are kept in reserve at a distance, hoping to hunt down any fleeing transports that have disengaged and split away. Knowing that their best chances for survival lie in maintaining formation, not even the captains of the Navis Mercantilis will disengage from this battle unless forced. To represent this, the transports in the Imperial convoy may only disengage if they have been crippled. If able to disengage successfully, it is assumed that they have made it to safety (see Victory conditions). All other ships on either side may disengage as normal.

Game length The battle continues until either fleet has disengaged or been destroyed.

Victory conditions Naturally, the success or failure of the convoy depends on how many transports survive the attack. Calculate the percentage of surviving transports based on transport capacity points. Crippled transports count as having lost half their cargo (i.e. transport capacity points), rounding down. 0% survival – The entire convoy has been annihilated, and the defeat is a major blow to the Navis Mercantilis and the many Imperial worlds, armies and fleets awaiting supplies. 30% survival – Most of the convoy is destroyed, but the Imperial fleet is able to drive away the attackers. The attackers are victorious, though perhaps not to the extent that they had hoped. 60% survival – While some ships have been lost or significantly damaged, the Imperial escorts are able to avoid disaster and defend their vulnerable transports. The convoy will reach its destination with most of its supplies intact. 90% survival – The convoy is virtually unscathed, despite the ferocity of the attack. The attackers have suffered a critical defeat, as their ships have been either lost or badly damaged and the Imperial convoy has not been stopped from reaching its destination. The Emperor protects!

Building merchant vessels To play battles with the Navis Mercantilis in Battlefleet Gothic, you’re going to need miniatures to represent the merchant vessels, of course. As it happens, Games Workshop and Forgeworld produce a lot of lovely models already. The basic ‘freighters’ from Games Workshop could easily be used to represent clippers or freighters, while ‘system ships’ can be used to represent caravels. The ‘heavy transports’ sold by Forgeworld can be used to represent galleons or carracks. If you want bigger transports, or if you want some more variety in your merchant fleet, you’re going to have to convert some miniatures!

Example 1: Galleon sprint trader You will need: - 1 Monitor ship (sold by Games Workshop) - 1 Imperial cruiser hull and 2 Imperial launch bays - 1 Chaos cruiser bridge and antennae - 2 Cadia pattern lasguns from Warhammer 40,000 Assorted plasticard and bitz for decoration and gapfilling.

Step 1: Use the bottom half of the Imperial cruiser hull. Cut the monitor ship in half, using its hull as part of the cruiser hull and keep its prow separate.

Step 2: Insert a 2 mm plasticard plate in the center of the Imperial cruiser’s plastic hull. It should fit perfectly.

Step 3: Cut off the spiky bits on the launch bays and cover the empty holes with plasticard.

Step 4: 4: Glue a launchbay on each side of the center plasticard. Attach the prow.

Step 5: Cut a Cadian lasgun into tiny pieces. Cut away some of the dorsal fin and insert a bridge for the ship.

Step 6: Insert the lasgun bitz in the gap between the monitor ship hull and the Imperial cruiser hull.

Example 2: 2: Super heavy barge barge

You will need: - Plasticard of different thicknesses (e.g. 2mm, 1mm and 0.5 mm) - 2 standard Imperial cruisers - 6 Imperial lance batteries, 6 Imperial launch bays (but preferably 12) - Bridge from Imperial or Chaos models. - Lots of various other bitz!

The process of converting this ship was incredibly complicated, so doing a step-by-step guide would require four or five pages. Furthermore, it would probably be pointless because such large conversion projects are always going to require a fair bit of creativity and improvisation anyway! Thus, I present these few images as a simple example of how one can create a super-heavy barge, a gargantuan merchant vessel bigger even than the battleships of the Imperial Navy!
