TNE Only: Brilliant Lances Technical Booklet Area Jammers

[snrdg082102]

Hello all,

Does anyone know what the radius of effect in kilometers that the Area Jammers listed on Brilliant Lances Technical Booklet (BLTB) 0303/R2 1993 that the volume, mass, mega-watts, and MCr show in the table on page 8 were calculated at?

Following the TNE FF&S Mk 1, Mod 1 (January 1994) Area Jammer design rules on page 53 I was able to verify that the BLTB TL-11 Area Jammer's radius of effect is 50,000 km. The other four entries I came close to the table entries and with rounding could make a match.

According to Consolidated TNE Errata v0.02 09/15/09 entry for Brilliant Lances that some errata was covered in the in TNE FF&S errata.

the TNE FF&S Mk 1, Mod 1 (January 1994) Area Jammer errata added the note that the antenna size in square meters is determined by MW ÷ 50. BLTB does not included the Antenna size entry.


I think that Brilliant Lance Technical Booklet needs to have an errata entry adding the radius of effect in kilometers, once they are determined, and to add the antenna surface area required.

In the absence of any further information, you've got a fair radius of effect already worked out.

As for the surface area, if this is a TL11 item wouldn't the surface area be negligible? Wouldn't you just be looking at the transmission array, which could be fairly small? What's the size of a similar item on an aircraft or naval vessel today?

Area Jammers have an area of effect of the hex the jammer is in, plus the six surrounding hexes. That's from p. 13 of the Rules of Play booklet.

Each map hex is listed as 30 000 km, or a tenth of a light second.

It said that area jammers work by flooding the area with as much EM noise as possible, so I don't know if there's a set minimum antenna size.

Hello Ulsyus,

Thanks for the reply and asking about the surface area of real world systems.

In the absence of any further information, you've got a fair radius of effect already worked out.

As for the surface area, if this is a TL11 item wouldn't the surface area be negligible? Wouldn't you just be looking at the transmission array, which could be fairly small? What's the size of a similar item on an aircraft or naval vessel today?

The TL-11 Area jammer is the only one that uses the 50,000 km radius returns the specified number in the Brilliant Lances Technical booklet page 8. The TL 10, 12, 14, and 16 area jammers numbers don't match up when 50,000 km is used.

The antenna surface area for the TL-11 area jammer antenna works out to be 1 square meter. Consolidated TNE Errata for FF&S uses the power in MW divided by 50 to determine the antenna surface area.

Per TNE FF&S page 53 MW = MW TL Mod x radius. The TL 11 MW mod is .001. MW = .001 x 50,000 = 50.

The antenna area = 50/50 = 1 m^2.

Unfortunately, I haven't taken the time to look at a real world example so I don't know the information.

Hello jcrocker,

Thank you for providing the Brilliant Lances (BL) info about area jammers in the Rules of Play.

Area Jammers have an area of effect of the hex the jammer is in, plus the six surrounding hexes. That's from p. 13 of the Rules of Play booklet.

Each map hex is listed as 30 000 km, or a tenth of a light second.

It said that area jammers work by flooding the area with as much EM noise as possible, so I don't know if there's a set minimum antenna size.

TNE FF&S page 53 indicates that the designer is not restricted to 60,000 km as BL does. However the ranges I worked out are within the BL 60,000 km area.

Of the other four remaining area jammers in Brilliant Lance's table the TL 12 and TL 14 systems, with rounding, the radius is 44,444 km. TL 16 unfortunately for the listed volume the radius is 44,092 km and the power requirement is for a radius of 44,444 km. The TL 10 area jammer the radius is 46,875 km and 47,500 km to match the power output.

The Consolidated TNE Errata for Brilliant Lances refers one to the FF&S errata section. According to the TNE Errata for FF&S the antenna size is equal to MW/50.

I wondering if the Brilliant Lances Area Jammer Table should be submitted as errata and set all the TL to the same radius.

Thank you again to the reply.
