So as I was sitting on my porch having my morning coffee, I saw a flight of five pelicans pass by. I couldn\u2019t believe my eyes: I saw them execute a Thach Weave! They were in a standard V and in the right \u201cwing\u201d the two birds swung behind each other, one after the other. As soon as they were done, the two in the left wing did likewise. After that, both \u201cwings\u201d together did the same \u2013 two birds in the right wing turned and passed behind left wing, and as they did so the left \u201cwing\u201d swung into place as the right wing. And they did it again, with the final result that all five birds were in the same relative position as they had been at the start. I thought to myself, That\u2019s amazing!<\/em> and at once it occurred to me that pelicans normally glide by without flapping a wing. This took a lot of effort.<\/p>\n Then I decided to check out the Thach Weave with AI. The result follows.<\/p>\n Question:<\/b><\/p>\n Describe the U.S. WWII defensive aerial maneuver called the Thach Weaver as performed by a two aircraft formation.<\/p>\n GPT-5 mini:<\/b><\/p>\n The Thach Weaver is a two-plane defensive aerial maneuver developed by U.S. Navy aviator John S. Thach in WWII to counter more maneuverable enemy fighters (notably the Mitsubishi A6M Zero). It uses coordinated turns and mutual support so that an engaged wingman can draw an attacker into the crossfire of the second friendly plane.<\/p>\n How it\u2019s flown (two-aircraft formation \u2014 Lead and Wingman)<\/p>\n Setup<\/b><\/p>\n Formation: loose wing or section with Lead and Wingman roughly 200\u2013400 feet apart.<\/p>\n Altitude\/speed: maintain safe separation and energy (speed) so both can maneuver together.<\/p>\n Initiation<\/b><\/p>\n When an enemy attacker engages one friendly (typically chasing Lead), both friendly pilots recognize the attack and begin a synchronized, weaving turn pattern.<\/p>\n Each pilot turns in opposite directions relative to the attack: typically the attacked ship (Lead) initiates a hard, defensive turn toward the wingman\u2019s side (i.e., toward the formation), while the Wingman turns outward or in the complementary direction so their flight paths cross.<\/p>\n The weave and mutual support<\/b><\/p>\n The two aircraft fly reciprocal, sweeping turns\u2014one turns inside while the other turns outside\u2014so their flight paths periodically cross, forming a \u201cweave.\u201d<\/p>\n As the attacker follows one friendly through a turn, that friendly\u2019s turn brings them toward the other friendly\u2019s firing position; when the attacker overshoots or follows too closely, the second friendly can get a firing solution.<\/p>\n The pattern forces the attacker to choose: stay on one target and risk being fired on by the other, or break off, losing pursuit.<\/p>\n Timing and spacing<\/b><\/p>\n Turns are synchronized in radius and timing so crossing points are predictable; safe spacing prevents collision while keeping the attacker inside effective firing angles for the second fighter.<\/p>\n Pilots maintain visual contact with both the attacker and each other; the Wingman watches the attacker\u2019s angle-off and time to firing position.<\/p>\n Attack-counterattack sequence (typical)<\/b><\/p>\n Attacker lines up on Lead.<\/p>\n Lead turns toward Wingman; attacker follows.<\/p>\n Wingman turns to present a shot opportunity as the attacker is committed to the chase.<\/p>\n Wingman fires when the attacker overshoots or comes into view; Lead may then reverse roles if needed.<\/p>\n Tactical effects and tradeoffs<\/b><\/p>\n Strengths: turns one-on-one disadvantages into a mutual-defense; exploits an attacker\u2019s tendency to fixate and overcommit; requires no external reinforcements.<\/p>\n Weaknesses: depends on coordination, timing, and spacing; risky at very close ranges or with poor visibility; less effective against disciplined attackers who refuse to chase into the weave.<\/p>\n Simple mnemonic of roles<\/p>\n Lead<\/u>: bait and inside turn toward Wingman.<\/p>\n Wingman<\/u>: mirror\/complementary turn, pick off the attacker when he commits.<\/p>\n That is the Thach Weaver in two-aircraft form: coordinated, crossing turns that convert an attacker\u2019s pursuit into an opportunity for the teammate to get a shot.<\/p>\n Question:<\/b><\/p>\n Describe a Thach Weave performed by a three aircraft formation.<\/p>\n GPT-5 mini:<\/b><\/p>\n Thach Weave \u2014 three-aircraft execution<\/p>\n Setup<\/b><\/p>\n Formation: three planes in a loose V or finger-four \u201csection\u201d with the leader (Lead) and two wingmen (Left and Right) spaced about 200\u2013500 ft laterally and slightly staggered fore\/aft.<\/p>\n Roles: Lead acts as initial bait\/decider; the two wingmen act as mutual \u201chooks\u201d to punish an attacker.<\/p>\n Basic idea<\/p>\n Instead of two planes weaving, the three-plane weave creates overlapping crossing paths so any attacker who commits to one defender is exposed to one or both of the other defenders as they cross into firing angles.<\/p>\n How it\u2019s flown (concise sequence)<\/b><\/p>\n Detection: An enemy commits to one friendly (e.g., on Lead or one wingman). All three keep visual contact.<\/p>\n Immediate response: The wing opposite the attacked ship (the \u201coutside\u201d wing relative to the attack) and the attacked ship begin complementary turns so their flight paths will intersect ahead of the attacker.<\/p>\n If Lead is attacked from behind\/above, Lead turns toward the attacking side; the two wingmen coordinate so one turns inside toward Lead and the other provides depth\/cover by turning to cut off escape or deliver another firing pass.<\/p>\n Weave pattern: The three aircraft weave in a staggered, synchronized fashion \u2014 the attacked ship and the nearest wingman cross first, then the other wingman times a crossing or high-speed intercept to present a converging shot.<\/p>\n Engagement point: As the attacker follows the bait through a turn, one wingman times a pass across the attacker\u2019s projected flightpath (or dives from a slightly different plane of motion) to obtain a firing solution when the attacker overshoots or becomes beam-on.<\/p>\n Role switching: After a firing pass or if the attacker breaks off, the three re-establish spacing and can repeat the weave or transition to other defensive\/offensive maneuvers.<\/p>\n Tactical variations and notes<\/b><\/p>\n Two-against-one focus: Often one wingman plays the immediate \u201chook\u201d while the third provides depth (a second hook or a cover\/overwatch pass), increasing redundancy versus a two-plane weave.<\/p>\n Altitude\/depth use: The third aircraft can use a slightly different altitude plane to create vertical crossing angles (dive or climb) that complicate the attacker\u2019s pursuit.<\/p>\n Spacing & timing: Larger lateral spacing makes crossings safer and gives longer firing windows; tighter spacing shortens reaction time but increases kill opportunities if well timed.<\/p>\n Advantages: More coverage and redundancy than a two-plane weave; harder for a single attacker to commit without being exposed to multiple firing angles.<\/p>\n Risks: Requires tighter coordination and clear visual contact; poor timing can leave one defender isolated or risk mid\u2011air conflicts.<\/p>\n Practical example (typical roles)<\/b><\/p>\n Lead attracts attack and turns toward the formation.<\/p>\n Nearest wingman \u201chooks\u201d inside, crossing the attacker\u2019s path to shoot when the pursuer overshoots.<\/p>\n Far wingman times a high-speed crossing or diving pass to either finish the attacker or discourage further pursuit.<\/p>\n Outcome<\/b><\/p>\n The three-plane Thach Weave increases the probability that any attacker who fixates on one aircraft will be confronted by one or both teammates as their flightpaths cross, turning a single-target chase into a multi\u2011axis defensive counterattack.<\/p>\n Search Results Question:<\/b><\/p>\n Is it possible to perform a Thach Weave with a five aircraft formation? Was this done in practice during WWII? If so describe the tactic. If not, use the foregoing to develop a “Thach Weave for Five” tactic. Estimate how many enemy aircraft could be held off by five coordinated planes flying a “Thach Weave for Five” tactic. Provide diagrams if possible.<\/p>\n GPT-5 mini:<\/b><\/p>\n Short answer<\/p>\n Yes \u2014 the Thach Weaver concept can be extended to five aircraft. It was not a widely recorded formal WWII tactic at that size, but squadrons used variations of mutual-support weaving and \u201csection\u201d tactics that produced similar effects. Below is a practical \u201cThach Weave for Five,\u201d how it would be flown, a simple estimate of defensive capacity, and two ASCII diagrams.<\/p>\n Assumptions and formation<\/b><\/p>\n Aircraft type: single\u2011engine fighters with similar performance (WWII-era prop fighters).<\/p>\n Visual contact maintained among the five; typical spacing 300\u2013800 ft laterally, 200\u2013600 ft fore\/aft, with modest altitude stagger (+\/\u2212 50\u2013200 ft) possible.<\/p>\n Roles: Leader (L), two inner wingmen (IL, IR) immediately left\/right, two outer wingmen (OL, OR) slightly wider outboard. Think of a shallow W or finger\u2011four extended to five.<\/p>\n Basic idea<\/b><\/p>\n Extend the two\u2011ship weave\u2019s crossing-turn concept across five aircraft so attackers committed to any single defender are exposed to multiple crossing firing opportunities from neighbors. Use overlapping pairs\/triples that weave in coordinated timing so an attacker is funneled into converging interception paths.<\/p>\n Formation option (preferred)<\/b><\/p>\n Shallow W: L near center-front, IL and IR close on his rear\/shoulders, OL and OR slightly aft and wider outboard.<\/p>\n This gives three echelons: front (L), middle (IL\/IR), outer rear (OL\/OR).<\/p>\n Maneuver sequence (step-by-step)<\/b><\/p>\n Detection and assignment<\/p>\n All five maintain visual. If an attacker commits to one ship (target), the whole section goes into weave mode.<\/p>\n Nearest mates to the target assume immediate \u201chooks\u201d; others prepare secondary intercepts or depth cover.<\/p>\n Initiation (timed complementary turns)<\/p>\n The attacked ship turns toward the nearest wingman (as in classic Thach).<\/p>\n That nearest wingman turns outward\/complementary so their flight paths will cross ahead of the attacker.<\/p>\n The outer wingman on the attacked side (\u201couter-hook\u201d) times a crossing behind\/through the attacker\u2019s projected track (slightly higher or lower) to present a second firing solution.<\/p>\n The opposite-side pair (on the far side of formation) tighten or trail as depth \u2014 they can either (a) maintain spacing to intercept if attacker breaks through, or (b) perform an angled cross to create another converging firing lane.<\/p>\n Overlapping hooks<\/p>\n Rather than a single crossing point, create overlapping crossing windows:<\/p>\n Immediate hook: attacked + inner wingman crossing.<\/p>\n Secondary hook: attacked + outer wingman crossing (larger radius\/altitude difference).<\/p>\n Tertiary coverage: opposite side inner+outer time a crossing to cut escape or punish multiple attackers.<\/p>\n Vertical separation and timing<\/b><\/p>\n Stagger OL\/OR a few dozen to a few hundred feet higher or lower; this lets them dive\/climb through different planes so an attacker cannot simply follow one turn without being exposed vertically.<\/p>\n Synchronize turn radii so crossings are predictable and collisions avoided.<\/p>\n Engagement and role rotation<\/b><\/p>\n When a wingman obtains a firing solution, others continue weaving to either present additional fire or cover any counterattack.<\/p>\n After a pass, reform into the shallow W and be ready to repeat or disengage.<\/p>\n Tactical variants<\/b><\/p>\n Concentrated pair-weave: collapse into two weaving pairs plus one floater\/cover (e.g., IL+L and IR+OL weave while OR provides overhead cover).<\/p>\n Rolling hooks: continuously cycle which pair performs the primary hook so no single defender is always bait.<\/p>\n Altitude ladder: use OL\/OR at differing altitudes to create cross-plane traps.<\/p>\n Practical considerations & risks<\/b><\/p>\n Requires high discipline, clear visual contact, and practiced timing. Collision risk increases with more aircraft.<\/p>\n Works best vs. small numbers of attackers (1\u20134) that attempt classic \u201ctail chase.\u201d Less effective against coordinated disciplined attackers or when overwhelmed.<\/p>\n Radio or preset visual signals recommended for timing.<\/p>\n Historical note<\/b><\/p>\n WWII records show many section and division mutual-support patterns and adaptations of the Thach concept to larger groups (e.g., sections of four or carrier group cover tactics). Explicit five\u2011plane Thach Weave descriptions are rare; squadrons improvised similar multi\u2011ship mutual\u2011defense weaves in practice.<\/p>\n Estimated defensive capacity<\/b><\/p>\n Conservative estimate: five coordinated fighters flying this tactic effectively hold off or deter approximately 2\u20134 attackers simultaneously (single\u2011engine fighters intent on close pursuit), with diminishing returns beyond that.<\/p>\n Rationale: each attacker committed to one defender risks exposure to at least one of the other four. With good timing, two attackers can be engaged sequentially by different hooks; three attackers can be handled if they attack in sequence or are spaced apart; four or more coordinated attackers can overwhelm pairing timing and force defenders to split.<\/p>\n Factors that change this estimate: pilot skill\/coordination (can increase capacity), aircraft performance mismatch (e.g., much faster attacker reduces effectiveness), visibility, and altitude.<\/p>\n Simple ASCII diagrams<\/b><\/p>\n Two-step crossing example (attacker coming from rear center to target L):<\/p>\n Step A \u2014 Target (L) turns toward the nearest wing (IL); IL turns outward so their flight paths will cross ahead of the attacker. OL begins a slightly higher-radius, delayed turn to time a secondary crossing from above\/behind.<\/p>\n Step B \u2014 As the attacker follows L through the inside turn, IL\u2019s outside turn brings IL\u2019s nose across the attacker\u2019s projected flightpath; IL readies a firing pass when the attacker overshoots or becomes beam-on. OL completes the delayed higher\/larger-radius crossing to offer a second firing angle if the attacker tries to continue the chase or overshoots IL.<\/p>\n Step C \u2014 Simultaneously on the opposite side, IR and OR tighten spacing and either (a) perform a delayed cross to block lateral escape routes, or (b) hold as depth cover to intercept any attacker who breaks away. If the attacker commits to IL instead, roles swap: IL becomes bait while L or OL executes the hook.<\/p>\n Step D \u2014 After a firing pass by IL (or OL), the group immediately re-establishes the shallow W spacing and altitude ladder. If the attacker is still active, the next timed hook (IR or OR) executes; if multiple attackers are present, hooks are sequenced so each pursuer is funneled into an available crossing window.<\/p>\n Notes on timing and spacing<\/b><\/p>\n Crossing windows: make them wide enough for safe interception but tight enough to force attackers into predictable overshoot positions (typical lateral spacing 300\u2013800 ft; timing offsets ~1\u20133 seconds between inner and outer hooks).<\/p>\n Vertical offset: OL\/OR 50\u2013300 ft different from IL\/IR helps create vertical crossing planes and reduces collision risk.<\/p>\n Signals: use brief wing waggle or radio call to start the weave when an attack is detected.<\/p>\n Diagram (top view, sequence)<\/p>\n Initial:<\/p>\n \nInitial shallow W formation (top view; arrows show nominal forward direction):<\/p>\n Step A (L turns toward IL; IL turns outward; OL delays\/high):<\/p>\n Step B (IL crosses attacker; OL dives\/angles through later):<\/p>\n Reform:<\/p>\n Estimated engagements<\/b><\/p>\n Well\u2011flown, five fighters using this pattern can reliably deter or sequentially engage ~2\u20134 single attackers; handling more requires superior pilot skill, altitude advantage, or splitting into paired weaves plus a floater cover.<\/p>\n If you want, I can draw clearer schematic diagrams (ASCII or vector) showing turn arcs and timing offsets.<\/p>\n But while I find AI an interesting tool and a way to gather information quickly, I still would never trust it to make decisions!<\/p>\n","protected":false},"excerpt":{"rendered":" What You Can Do with AI So as I was sitting on my porch having my morning coffee, I saw a flight of five pelicans pass by.
