In ãRedemption, Pt. Iä, the Bortas was engaged by a pair of KâVort-class battlecruisers. The first shots fired in the battle appeared to have hit Bortas while she
was unshielded; nevertheless, she was able to raise shields only to lose them in an impressive show of defensive capability. Once her shields failed and Bortas appeared all but crippled, her crew lured the two KâVorts into transporter range, in the hopes that the aggressors would lower shields and try to board the Vorâcha-class ship.

The ploy was successful. Targeting the forward disruptor cannon manually, Bortas was able to fire a single shot and destroy an unshielded KâVort - the second K'Vort raised its shields in time to avoid destruction. KâVort class ships are thought to have roughly thrice the dimensions of its smaller cousin, the BâRel Bird of Prey/scout: 300m length, 60m height. And again, to use the original Enterprises as a means of mass comparison, the KâVort probably has a mass of 800,000 to 1,000,000 mt. Assuming an average density of some 300 kg/m³, the volume of the K'Vort would be some 3,000,000 m³. Since we know it takes 2.4 x 10¹² MJ to vapourise a cubic metre of tritanium, then had the the K'Vort been made of solid metal it would take some 7,200,000 TeraJoules to vapourise it. Since only about 0.1% of the ship could actually be expected to really be metal, then the overall power would be 7,200 TJ

But first, to find more accurate figures for the SHC and MP of the KâVortâs constituent metals, we should move forward several seasons and to a new show
altogether: ãReturn To Graceä. This episode provides a meaningful comparison of a BâRel-classâs metal durability with that of an asteroid no less than 20
metres in diametre.
Groumall, a Cardassian military freighter operated for a short time by Gul Dukat, was equipped with some sort of low-powered particle beam that she
tested with limited success on asteroids. When this particle beam failed to penetrate the hull of an unshielded Bird of Prey--let alone provoke the Klingons to
attack or raise shields--Dukat acquired a System V planetary disruptor from an outpost the Klingons had destroyed. In similar tests, the disruptor easily dispatched
slightly larger asteroids with discharges of .5 seconds or less. We will assume the asteroids were of ferrous (iron) composition and were not completely vaporized; further, we will assume an initial temp. of approximately 206 K.

V = pi*(20)³/6
= 4187 m³
D = 7860 kg/m ³
M = 32,909,820 kg

E = 32,909,820*447*1603
= 23,581,364,310,000 joules; 23 terajoules

Increasing the number eight-fold would give us a rough idea of the E requirements for totally vaporizing a 20m-diametre asteroid, but again, Groumall only vaporized 50% or so of the mass. Therefore, we will split the difference and conclude the energy required to half-melt, half-vaporize the asteroid was:

= 4 * 23,581,364,310,000
= 94,325,457,240,000 joules; 94 terajoules

To reiterate, this blast was delivered to the asteroid in about a half-second. Thus, the power of Groumallâs disruptor is no less than 188 terawatts.
Later in ãReturn To Grace,ä while the Klingons tractored the Cardie frieghter and did not raise shields, Groumall brought her disruptor to bear on the Bird
of Prey and destroyed a portion of their hull, measuring approximately 10m in diametre.
Assuming the Bird of Prey has a density of 300 kg/m³--that of modern ocean liners (again courtesy of the PP)--a 10m-wide hole in the ship would enclose
no more than:

V = pi*(10)³/6
= 523m³

M = V*D
= 156,900kg

The asteroid had a mass of 32,909,820 kg, some 210 times less than the destroyed portion of the Bird of Prey. (Note: There appeared to be some
fragmentation from the BoPâs hull, but some vaporization of materials took place. Therefore, the apparent disparity in final states of matter in each should in fact be
relatively similar, if on the conservative side.) However, the energy used to destroy each was the same; the duration of the disruptor beams was even
similar. We can only conclude that the Bird of Preyâs hull is roughly 210 times more difficult to damage than the iron asteroid.
Relative to the Vorâcha class, we can start with values for Fe and use 210 as a multiplier to find more accurate estimates of Bortasâ firepower when already
crippled. Making a conservative estimate for KâVortâs mass--800,000mt, or 881,600,000 kg--we find the following. (Note: .5 denotes the KâVort being taken to only half its melting point. There was no debris visible from the Vorâchaâs attack; however, in the continuing spirit of conservation, we will assume the destruction was somewhat less than it appearead to be.)

E = 881,600,000 * 447 * (1809K - 305K) * .5 * 210
= 296,344,550,400,000 * 210
= 62,232,355,584,000,000 joules; 62,232 terajoules

The disruptor bolt was fired in no more than .5 seconds; quite possibly, as few as .25 of a second, though such a figure would not be reasonable to
associate with a badly damaged ship losing power. Assuming .5 seconds, the firepower of the Vorâcha forward disruptor cannon is 124,464 terawatts. (Compared to the GCS phaser output at 1*10⁵ TW, this perfectly matches the speculation in the starship statistics section!)

Vaping a 800,000 ton of Al would take... E = 900 x 8e8 x 2435 = 1.7532 x 10¹⁵ J

Tritanium is 450 x tougher, so... E = 7.8894 x 10¹⁷

In 0.5 seconds = 1.57788 x 10¹⁸ W = 1,577,880 TW

MP of Al = 1400????
Melting 800,000 ton of Al would take... E = 900 x 8e8 x 1100 = 7.92e+14 J
