History of Isselmere-Nieland
Ranks and insignia

The Defence Procurement Agency (DPA) is a department within the Isselmere-Nielander Ministry of Defence responsible for the examination, acquisition, adoption, and inspection of goods and services for that nation's Defence Forces.


In 1954, the DPA replaced the various ordnance and matériel bureaux operated by the various armed services, specifically those of the Army and Navy. For the most part, it has maintained the traditions of its predecessors, much to the consternation of civilian authorities, but certain improvements — such as the establishment of the Uniform Electronic Devices Index — have proven immensely successful.


The DPA is administered by a minister of State, a senior member of government ranking beneath a minister.

The DPA is organised into four directorates-general (DG), each headed by a director-general:

  • Directorate-General for Aviation
  • Directorate-General for Land Systems
  • Directorate-General for Naval Systems
  • Directorate-General for Space Systems

Guided Systems Index

The Guided Systems Index (GSI) was introduced in 1957 to cover most forms of guided devices, other than uncrewed vehicles, as well as their launchers. Extended range guided munitions (ERGM) for heavy artillery pieces are not usually included within the GSI, but instead are listed under INO numbers.

GSI numbers comprise of a three or four letter prefix — GDS for guided/autonomous decoy system, GWS for guided weapon system, and GWLS for guided weapon launcher system — followed by the model number in Arabic numerals. After the model number comes the launch environment indicator, which usually provides the first letter indicator for the UKINDF's Services Pilotless Vehicles Index (SPVI) number. Next comes the mark number in Arabic numerals. This might be followed by a modification indicator, a minuscule letter.

e.g. GWS.41M2b

Broken down, the example above describes Guided Weapon System number 41, Surface ship, Mark 2, 2nd modification. According to the SPVI, this same device is classified as MUM.41B2 for Surface ship version, Underwater attack missile, Model 41, Version B, Modification 2.[1]

New GSI numbers are usually given to systems that are significant different from their predecessors. Mark numbers indicate slight modifications to the existing system, which is corollary to the version indicator in the SPVI. Unfortunately, sometimes what the DPA justly considers a modification the UKINDF rightly considers a version. Case in point:

GWS.65Aa Kite infrared-guided air-to-air missile (GSI) = AIM.65A (SPVI)

To reduce this confusion, GSI modification indicators typically correlate with the SPVI version indicators.





GWLS.68M: 2 × 8-cell GWLS.65 VLS with Goalkeeper CIWS
GWLS.68M2: 2 × 8-cell GWLS.65 VLS with L72A3 (MCA.72) 35mm autocannon


GWLS.98M: 2 × 8-cell GWLS.76M with 57mm autocannon[11]


GWLS.103M: 2 × 35 mm L72A2 + 2 × 4-cell GWS.85 Vulture

Logistics and Ordnance numbers

Logistics and Ordnance numbers, often termed Isselmere-Nieland Ordnance numbers (INO numbers) are provided for small arms, crew-served weapons, artillery pieces, and ground vehicles, the last category being divided into support and fighting vehicles. The numbers for these items usually begin with L for Land Service despite being used — often in a much-modified condition — by several services at once, sometimes not including the Army. Across the five categories, there may be several items with the same basic L number, in which case the full designation for an item in question is typically used in records and reports.

Certain naval artillery pieces have designation numbers beginning with M, indicating a device that was either solely or primarily developed for naval use. Where an M number for an artillery piece exists, there is no corresponding L number, and vice versa.

Munitions, including small arms ammunition and ordnance (shells, unitary rounds, artillery and other light rockets), are designated by LM for Land Munitions or in certain instances by MM for Marine (Naval) Munitions. Propellant charges are indicated by INP.

Certain weapons possess a designation beginning with three letters similar to the UKINDF-USDS format, such as the ACA.41 30mm autocannon. Such a designation is not entirely accurate. The proper full form would in fact be the L41A1, 30mm cannon, Automatic, Aircraft, usually shortened to simply L41A1, with "-A1" indicating an alteration to the basic L41 design.


Rockets as components of guided weapons possess their own designation system. All such designations begin with the letter R. Next is the device type designator:

  • (number) = Stage, indicates the stage of a rocket that forms part of its main body.
  • B = Booster, a rocket that attaches to the main body of the device or otherwise not part of the whole.
  • E = Engine, followed by the fuel-compound designator.
  • M = Motor, usually used for the stage of a one- or two-stage rocket conveying the payload to the objective.
  • P = Payload, a rocket attached to the payload, primarily for manoeuvring, slow burn, or a short boost.

The Stage, Booster, Motor, and Payload designators are followed by a general fuel designator, which is typically L for liquid propellant (kerosene, etc.) or S for solid rocket propellant. After the general fuel designator comes the complete system's DPA number:

e.g., R1S.97, for the first stage of the GWS.97 Ahab anti-ship missile.


  1. ^  There was no "Modification 1" of the MUM.41B or UUM.41B that became operational in UKINDF service. Modification 1 was to have had a MU90 Impact torpedo atop the longer-ranged carrier, but it was replaced by the GWS.63 Barracuda (i.e., "Modification 2").
  2. ^ The UKIN government sought to obtain the UGM-27 Polaris A3 missile from the United States of America but was rebuffed at the last moment.
  3. ^ a  Product of United Elias.
  4. ^ 
  5. ^ 
  6. ^ a b  Product of Sarzonia.
  7. ^ 
  8. ^  Formerly known as the ALQ.220 and the ADQ.220. The re-designation to ADM (air-launched active decoy) led to its re-classification and receiving a DPA number.
  9. ^  In its experimental stages, it was known as the ALQ.301 and the ADQ.301. Like the Flamingo, its re-classification led to a DPA number.
  10. ^  Collaborative project with Space Union.
  11. ^  GWLS.98 gun-missile complex with 57mm autocannon and two eight-cell GWLS.76M launchers.
