The SDR-5V Spider is the crowning triumph of the Newhart intersteller
industry's long history of armament manufacture. Though the firm
produced mostly aerospace fighters, the spider was their first and only
entry into the battlemech market.
In 2650, Star League requisitioned a special mech for its elite commando
forces. Newhart responded so quickly that most of the other mech
manufacturing firms were left sitting in the dust. Newhart had, in fact,
already designed the SDR series, which more than met the minimum
standards for a lightweight recon / attack mech. They were also ready
for production, and so the Star League awarded them the contract.
The Spider got its name from the fact that the frontal armor alignment
resembles a spiderweb pattern. The seams between armor plates are filled
with a fiber glass sealent that is bright red, making the pattern stand
out even more.
The SDR-5V was conceived as a fast - moving mech with ample fire power
and the ability to operate for an extended period of time without
support. To fulfill the latter requirement, very reliable parts were
used on the spider, which keeps maintance cycles to a minimum. The mechs
firepower consists of two center torso-mounted Aberdovey MK III medium
lasers. Though more expensive than the common Martell lasers, they are
considered top quality available.
Jump capacity set this mech above and beyond modified versions of the
Locust and other recon mechs. The jump jet system was designed to make
standard leaps as well as to vary the leap by pivoting the jets in
flight. Such actions tended to play havoc with even the most
sophisticated targeting systems.
The Spider's only real design flaw is that particular configuration of
armor and sensors leave no room for installation of a pilot escape
system. Thus, in care of emergency, the Spider pilot must make his way
manually to the lower hatch to exit the mech.
Very few SDR-5V spiders were left in the Successor States after the fall
of Star League/ When House Marik discovered a supply bunker with
several functional Spiders on the planet Keystone in their sphere, they
quickly absorbed the mechs into their forces.
In the battle for Styk within Davion space in 2934, units from Marik's
militia attacked units of Davion's Deneb Light Calvery's old 7th
regiment. While defending the ruins of the city of Devonshire, the Deneb
Light Calvary found itself under attack by the militia forces' several
Spiders. Using a series of close-combat attacks such as jumping, the
Spiders cut through Davion's outer defenses making it possible for Marik
forces to that the city for several hours, looting it of supplies.
In 2970 House Steiner made use of several Spiders in a fast raid on the
Kurita-held world of LaBlon. As part of the 12th Star Guards, the
Spiders moved in on the rear area of a Kurita supply dump. As they hit
one area, the other raiders struck in force from another location. This
tactic allowed Steiner to cut down the spread-out Kurita troops, which
could not rally in time to stop the attackers from taking the supplies
to their waiting Dropship.
House Davion was desperate to gain control of several Spiders to
supplement its own forces, as they had to scrap theirs for parts during
the first Succession war. In 3000, House Davion's elite First Guards
staged a commando-style raid on a mech repair facility on the House
Marik world Sirus. Far from their own territory, the attacking forces
dropped just ouside of the facility and took what they came for, five
Spiders that was brought in for research and preventive maintence.
Despite heavy damage given my Marik's support, the Guards took few
losses and succeeded in getting the Spider mech's they came for.
Another Military unit reported to have possession of Spiders is the
equally elite Wolf's Dragoons. Reports from various battlefields state
that the Dragoons make use of an entire lance of Spiders, though these
reports are not easily confirmed.
Two experimental versions of the SDR-5V have been discovered within the
Successor States. One version supports a single Aberdovey medium laser
and two Arkum flamers mounted on each of the arms. This version is used
primarily in Davion-controlled space. The other version, which is used
mainly by House Kurita troops, also has one medium laser and two machine
guns systems on each arms. It is designed primarily as an anti infantry
No BattleMech can match the SDR-5V when it comes to Speed and agility.
But while it possesses incredible maneuverability, it has very little
The SDR-5V sacrifices offensive capability for the ability to
effectively scout, harass, and generally sow chaos amongst enemy
formations. Two Medium Lasers provide reliable striking ability and
ammunition independence. Impressive speed allows the Spider to quickly
close in on enemy targets. However, the unparallelled jumping capability
is what truly allows the 'Mech to hit and fade quickly.
The SDR-5V can mount up to 12 Jump Jets, a full 50% more than its
nearest rival, the Spider SDR-5D. A 110° torso twist means the firing
arc isn't too limited by the lack of arm mounted weapons.
The -5V has very limited space to mount weapons. It is limited to only
two energy Hardpoints which share a maximum of two critical spaces in
its center torso.
The fact that all of its weapons are mounted in the torso means the
'Mech can possible survive the loss of both arms and side torsos and not
lose any of it's offensive ability, assuming a Standard Engine is
The SDR-5K retains much of the mobility of the earlier -5V. It decreases
the number of Jump Jets by two and one of the Medium Lasers to add two
Machine Guns to the design.
The SDR-5K has an unusual large amount of Ballistic Hardpoints available
to it, which (due to the BattleMech's weight) can be expected to be
mounted with Machine Guns in large number.
While it has a surplus of ballistic hardpoints, it lacks any real number
of energy or missile hardpoints. This severely restricts the choices of
light weight weapons it can mount.
The SDR-5D is one of the few 'Mechs capable of mounting ECM. Three
energy Hardpoints allow it to take advantage of the lightest weapons
available. Its impressive jumping capability is only surpassed by the
The SDR-5D is identical to the original -5V except that it drops one
Medium Laser in favor of a Flamer. Like the -5V, it possesses superior
jumping ability. The lack luster damage output is partially balanced by
the sheer speed and agility of the 'Mech.
Like all Spiders, the SDR-5D is capable of incredible Speed and
maneuverability. ECM allows the -5D to disrupt enemy sensors and
missiles. It is also able to counter enemy ECM to expose hidden units.
The -5D has one of the fewest number of weapon hardpoints of available
on a BattleMech, which limits the types of loadouts that can be loaded
The left arm lacks any weapon hard points and can be used as shield or
armor stripped off of it to allocate it to other equipment.
